Tetra­kis(2,3,5,6-tetra­fluoro­benzene­thiol­ato-κS)(tri­phenyl­phosphane-κP)osmium(IV): a monoclinic polymorph

The structure of the title compound, [Os(C6HF4S)4{P(C6H5)3}], has been previously reported [Arroyo et al. (1994). J. Chem. Soc. Dalton Trans. pp. 1819–1824], in the space group Poverline{1}. We have now obtained a monoclinic polymorph for this compound, crystallized from ethanol, while the previous form was obtained from a hexa­ne/chloro­form mixture. The mol­ecular structure is based on a trigonal–bipyramidal OsIV coordination geometry, close to that observed previously in the triclinic form.

The crystal structure of the triclinic polymorph of 1,4-bis­([2,2':6',2''-terpyridin]-4'-yl)benzene

The title triclinic polymorph (Form I) of 1,4-bis­([2,2':6',2''-terpyridin]-4'-yl)benzene, C36H24N6, was formed in the presence of the Lewis acid yttrium trichloride in an attempt to obtain a coordination compound. The crystal structure of the ortho­rhom­bic polymorph (Form II), has been described previously [Fernandes et al. (2010). Acta Cryst. E66, o3241–o3242]. The asymmetric unit of Form I consists of half a mol­ecule, the whole mol­ecule being generated by inversion symmetry with the central benzene ring being located about a crystallographic centre of symmetry. The side pyridine rings of the 2,2':6',2''-terpyridine (terpy) unit are rotated slightly with respect to the central pyridine ring, with dihedral angles of 8.91 (8) and 10.41 (8)°. Opposite central pyridine rings are coplanar by symmetry, and the angle between them and the central benzene ring is 49.98 (8)°. The N atoms of the pyridine rings inside the terpy entities, N⋯N⋯N, lie in trans–trans positions. In the crystal, mol­ecules are linked by C—H⋯π and offset π–π inter­actions [inter­centroid distances are 3.6421 (16) and 3.7813 (16) Å], forming a three-dimensional structure.

An indenide-tethered N-heterocyclic stannylene

Analysis of the coordination of the Sn to the indenyl ring shows that the Sn inter­acts in an η2 fashion. A database survey showed that whilst this coordination mode is unusual for Ge and Pb compounds, Sn displays a wider range of coordination modes to cyclo­penta­dienyl ligands and their derivatives.

Polymorphism of 2-(5-benzyl-6-oxo-3-phenyl-1,6-di­hydro­pyridazin-1-yl)acetic acid with two monoclinic modifications: crystal structures and Hirshfeld surface analyses

Two polymorphs of the title compound, C19H16N2O3, were obtained from ethano­lic (polymorph I) and methano­lic solutions (polymorph II), respectively. Both polymorphs crystallize in the monoclinic system with four formula units per cell and a complete mol­ecule in the asymmetric unit. The main difference between the mol­ecules of (I) and (II) is the reversed position of the hy­droxy group of the carb­oxy­lic function. All other conformational features are found to be similar in the two mol­ecules. The different orientation of the OH group results in different hydrogen-bonding schemes in the crystal structures of (I) and (II). Whereas in (I) inter­molecular O—H⋯O hydrogen bonds with the pyridazinone carbonyl O atom as acceptor generate chains with a C(7) motif extending parallel to the b-axis direction, in the crystal of (II) pairs of inversion-related O—H⋯O hydrogen bonds with an R22(8) ring motif between two carb­oxy­lic functions are found. The inter­molecular inter­actions in both crystal structures were analysed using Hirshfeld surface analysis and two-dimensional fingerprint plots.

Charge density view on bicalutamide molecular interactions in the monoclinic polymorph and androgen receptor binding pocket

High-resolution single-crystal X-ray measurements of the monoclinic polymorph of bicalutamide and the aspherical atom databank approach have served as a basis for a reconstruction of the charge density distribution of the drug and its androgen receptor (AR) and albumin complexes. The contributions of various types of intermolecular interactions to the total crystal energy or ligand:AR energy were estimated. The cyan and amide groups secured the ligand placement in the albumin (Lys-137) and the AR binding pocket (Leu-704, Asn-705, Arg-752), and also determined the packing of the small-molecule crystals. The total electrostatic interaction energy on average was −230 kJ mol−1, comparable with the electrostatic lattice energy of the monoclinic bicalutamide polymorph. This is the result of similar distributions of electropositive and electronegative regions on the experimental and theoretical molecular electrostatic potential maps despite differences in molecular conformations. In general, bicalutamide interacted with the studied proteins with similar electrostatic interaction energies and adjusted its conformation and electrostatic potential to fit the binding pocket in such a way as to enhance the interactions, e.g. hydrogen bonds and π⋯π stacking.

Structural elucidation of triclinic and monoclinic SFCA-III – killing two birds with one stone

A part of the system CaO-SiO2–Al2O3–Fe2O3–MgO which is of relevance to iron-ore sintering has been studied in detail. For a bulk composition corresponding to 10.45 wt% CaO, 5.49 wt% MgO, 69.15 wt% Fe2O3, 13.37 wt% Al2O3 and 1.55 wt% SiO2 synthesis runs have been performed in air in the range between 1100 and 1300°C. Products have been characterized using reflected-light microscopy, electron microprobe analysis and diffraction techniques. At 1250°C, an almost phase-pure material with composition Ca2.99Mg2.67Fe3+14.58Fe2+0.77Al4.56Si0.43O36 has been obtained. The compound corresponds to the first Si-containing representative of the M14+6nO20+8n polysomatic series of so-called SFCA phases (Silico-Ferrites of Calcium and Aluminum) with n = 2 and is denoted as SFCA-III. Single-crystal diffraction investigations using synchrotron radiation at the X06DA beamline of the Swiss Light Source revealed that the chemically homogenous sample contained both a triclinic and monoclinic polytype. Basic crystallographic data are as follows: triclinic form: a = 10.3279 (2) Å, b = 10.4340 (2) Å, c = 14.3794 (2) Å, α = 93.4888 (12)°, β = 107.3209 (14)° and γ = 109.6626 (14)°, V = 1370.49 (5) Å3, Z = 2, space group P{overline 1}; monoclinic form: a = 10.3277 (2) Å, b = 27.0134 (4) Å, c = 10.4344 (2) Å, β = 109.668 (2)°, V = 2741.22 (9) Å3, Z = 4, space group P21/n. Structure determination of both modifications was successful using diffraction data from the same allotwinned crystal. A description of the observed polytypism within the framework of OD-theory is presented. Triclinic and monoclinic SFCA-III actually correspond to the two possible maximum degree of order structures based on OD-layers containing three spinel (S) and one pyroxene (P) modules (〈S3P〉). The existence of SFCA-III in industrial iron-ore sinters has yet to be confirmed. Polytypism is likely to occur in other SFCA-members (SFCA, SFCA-I) relevant to sintering as well, but has so far been neglected in the characterization of industrial samples. Our results shed light on this phenomenon and may therefore be also helpful for better interpretation of the powder diffraction patterns that are used for phase analysis of iron-ore sinters.

ClickX: a visualization-based program for preprocessing of serial crystallography data

Serial crystallography is a powerful technique in structure determination using many small crystals at X-ray free-electron laser or synchrotron radiation facilities. The large diffraction data volumes require high-throughput software to preprocess the raw images for subsequent analysis. ClickX is a program designated for serial crystallography data preprocessing, capable of rapid data sorting for online feedback and peak-finding refinement by parameter optimization. The graphical user interface (GUI) provides convenient access to various operations such as pattern visualization, statistics plotting and parameter tuning. A batch job module is implemented to facilitate large-data-volume processing. A two-step geometry calibration for single-panel detectors is also integrated into the GUI, where the beam center and detector tilting angles are optimized using an ellipse center shifting method first, then all six parameters, including the photon energy and detector distance, are refined together using a residual minimization method. Implemented in Python, ClickX has good portability and extensibility, so that it can be installed, configured and used on any computing platform that provides a Python interface or common data file format. ClickX has been tested in online analysis at the Pohang Accelerator Laboratory X-ray Free-Electron Laser, Korea, and the Linac Coherent Light Source, USA. It has also been applied in post-experimental data analysis. The source code is available via https://github.com/LiuLab-CSRC/ClickX under a GNU General Public License.

Li-ion half-cells studied operando during cycling by small-angle neutron scattering

Small-angle neutron scattering (SANS) was recently applied to the in situ and operando study of the charge/discharge process in Li-ion battery full-cells based on a pouch cell design. Here, this work is continued in a half-cell with a graphite electrode cycled versus a metallic lithium counter electrode, in a study conducted on the SANS-1 instrument of the neutron source FRM II at the Heinz Maier-Leibnitz Zentrum in Garching, Germany. It is confirmed that the SANS integrated intensity signal varies as a function of graphite lithiation, and this variation can be explained by changes in the squared difference in scattering length density between graphite and the electrolyte. The scattering contrast change upon graphite lithiation/delithiation calculated from a multi-phase neutron scattering model is in good agreement with the experimentally measured values. Due to the finite coherence length, the observed SANS contrast, which mostly stems from scattering between the (lithiated) graphite and the electrolyte phase, contains local information on the mesoscopic scale, which allows the development of lithiated phases in the graphite to be followed. The shape of the SANS signal curve can be explained by a core–shell model with step-wise (de)lithiation from the surface. Here, for the first time, X-ray diffraction, SANS and theory are combined to give a full picture of graphite lithiation in a half-cell. The goal of this contribution is to confirm the correlation between the integrated SANS data obtained during operando measurements of an Li-ion half-cell and the electrochemical processes of lithiation/delithiation in micro-scaled graphite particles. For a deeper understanding of this correlation, modelling and experimental data for SANS and results from X-ray diffraction were taken into account.

A new monoclinic structure type for ternary gallide MgCoGa2

The crystal structure of MgCoGa2 (magnesium cobalt digallide) was solved by direct methods and refined in two space groups as P21/c (standard choice) and P21/n (non-standard choice). The refined lattice parameters for the standard choice are a = 5.1505 (2), b = 7.2571 (2), c = 8.0264 (3) Å and β = 125.571 (3)°, and for the non-standard choice are a = 5.1505 (2), b = 7.2571 (2), c = 6.5464 (2) Å and β = 94.217 (3)°. All parameters for MgCoGa2 refined to R1 = 0.027 and wR2 = 0.042 using 594 reflections. The crystal structure peculiarities of this compound are discussed. Particular attention has been given to relationships with other similar structures, such as YPd2Si and Fe3C. Crystallographic analysis, together with linear muffin-tin orbital electronic structure calculations, reveals the presence of three-dimensional polyatomic nets with partial covalent bonding between the Ga atoms.

CLIC4 is a cytokinetic cleavage furrow protein that regulates cortical cytoskeleton stability during cell division [RESEARCH ARTICLE]

Eric Peterman, Mindaugas Valius, and Rytis Prekeris

During mitotic cell division, the actomyosin cytoskeleton undergoes several dynamic changes that play key roles in progression through mitosis. While the regulators of cytokinetic ring formation and contraction are well-established, proteins that regulate cortical stability during anaphase and telophase have been understudied. Here, we describe a role for CLIC4 in regulating actin and actin-regulators at the cortex and cytokinetic cleavage furrow during cytokinesis. We first describe CLIC4 as a new component of the cytokinetic cleavage furrow that is required for successful completion of mitotic cell division. We also demonstrate that CLIC4 regulates the remodeling of sub-plasma membrane actomyosin network within the furrow by recruiting MST4 kinase and regulating ezrin phosphorylation. This work identifies and characterizes new molecular players involved in regulating cortex stiffness and blebbing during late stages of cytokinetic furrowing.

Serine 319 phosphorylation is necessary and sufficient to induce a Cx37 conformation that leads to arrested cell cycling [RESEARCH ARTICLE]

Samantha-Su Z. Taylor, Nicole L. Jacobsen, Tasha K. Pontifex, Paul Langlais, and Janis M. Burt

Connexin 37 (Cx37) expression profoundly suppresses proliferation of rat insulinoma (Rin) cells in a manner dependent on gap junction channel (GJCh) functionality and the presence and phosphorylation status of its carboxyl-terminus (CT). In Rin cells growth arrested by induced Cx37 expression, serine 319 (S319) is frequently phosphorylated. Preventing phosphorylation at this site (alanine substitution; S319A) relieved Cx37 of its growth suppressive effect whereas mimicking phosphorylation at this site (aspartate substitution; S319D) enhanced Cx37's growth suppressive properties. Like Cx37-WT, -S319D GJChs and hemichannels (HChs) preferred the closed state, rarely opening fully, and gated slowly. In contrast, Cx37-S319A channels preferred open states, opened fully, and gated rapidly. These data indicate that phosphorylation-dependent conformational differences in Cx37 protein and channel function underlie Cx37-induced growth arrest vs. growth permissive phenotypes. That the closed state of -WT and Cx37-S319D GJChs and HChs favors growth arrest suggests that rather than specific permeants mediating cell cycle arrest, the closed conformation instead supports interaction of Cx37 with growth regulatory proteins that result in growth arrest.

The business climate in Los Angeles

Business Update with Mark Lacter

We've been reporting on the city of Los Angeles approving major developments without seismic studies attached.

Steve Julian: Business analyst Mark Lacter, why is this?

Mark Lacter: Steve, this is a real gotcha moment for the L.A. Planning Department, the City Council, and everyone else at City Hall who signed off on these projects.  The latest revelation, which was reported by the L.A. Times, shows that a planned 39-story residential tower in Century City is just 300 feet from the active Santa Monica fault.  And, we're only learning about this because the Metropolitan Transportation Authority did its own seismic testing near the site when it was looking for potential subway stops, and officials decided that it was too close to the fault.  This also comes after three large-scale projects in Hollywood were found to be located quite close to the active Hollywood fault.

Julian: The concern is that if any faults were to rupture, the foundation of a building could be split apart.

Lacter: Kind of an inconvenient truth both for the developers, who have millions of dollars riding on these projects, and for L.A. city officials who are betting on a future that will include many more high rises.  And, we should note that more than two-dozen high rises are either in the process of going up, or are at least on the drawing board.  In case you're wondering why there aren't regulations that monitor this sort of thing, the answer is that there are regulations.  California has a law that requires state geologists to map active earthquake faults, and then set zones on either side of the fault line.

Julian: Has the state done this?

Lacter: The state says it hasn't had the time nor the money to map areas within the city of L.A., though the faults have been known to be in the general vicinity of these projects - and so, you'd think the city would want them tested extensively.  Of course, that would mean more delays, which the developers wouldn't be happy with.

Julian: Of course, seismic studies are not always definitive.

Lacter: They're not - and it's possible that different geologists would come up with different findings.  But so far, most of the information seems to be coming from the developers, and you have to wonder whether it's a great idea to rely on folks who have a financial interest in a project to tell us what's safe and what isn't.  Probably not.

Julian: Your article in the new issue of Los Angeles Magazine raises a broader point about the city's business climate.

Lacter: Steve, for many years, L.A. has been branded as a terrible place to do business because of government interference, but that's largely a myth.  If anything, city officials have been too accommodating.  Frankly, the anti-business rap never made much sense when you consider the thousands of companies that start up here each year.  A study by the accounting firm PricewaterhouseCoopers ranks L.A. particularly high when it comes to ease of doing business, which runs counter to the conventional wisdom.

Julian: You're not saying it's truly easy, are you?

Lacter: Easy, no.  There certainly are plenty of reasons for business owners to pull out their hair.  And those hassles, along with an unemployment rate that remains quite high, has given developers and others the leverage to ask for various giveaways.  All they have to do is say that their projects will generate more jobs, and city officials tend to respond favorably - no matter how questionable those proposals might be.  And, by the way, job creation doesn't always determine economic growth, certainly not in the short term.

Julian: We all remember during the mayoral campaign, candidates were talking about how their policies would lead to lower unemployment...

Lacter: ...right, almost like they could pick up jobs at Ralphs.  Well, it doesn't work that way.  Thing is, the city of L.A. doesn't need to cut so many deals - the local economy is rich enough and broad enough to keep prospering.  Which is why city officials would be much better off laying off the incentives, and focusing on the basics - public safety, transportation, the parks, and libraries.  Do that right, and the business climate will take care of itself.
