A molybdenum tris­(di­thiol­ene) complex coordinates to three bound cobalt centers in three different ways

The synthesis and structural characterization of the mol­ecular compound (μ3-benzene-1,2-di­thiol­ato)hexa­carbonyl­bis­(μ3-1,1,1,4,4,4-hexafluorobut-2-ene-2,3-dithiolato)tricobaltmolybdenum, [Co3Mo(C4F6S2)2(C6H4S2)(CO)6] or Mo(tfd)2(bdt)(Co(CO)2)3 (tfd is 1,1,1,4,4,4-hexafluorobut-2-ene-2,3-dithiolate and bdt is benzene-1,2-di­thiol­ate), are reported. The structure of the mol­ecule contains the molybdenum tris­(di­thiol­ene) complex Mo(tfd)2(bdt) coordinated as a multidentate ligand to three cobalt dicarbonyl units. Each of the three cobalt centers is relatively close to molybdenum, with Co⋯Mo distances of 2.7224 (7), 2.8058 (7), and 2.6320 (6) Å. Additionally, each of the cobalt centers is bound via main-group donor atoms, but each one in a different way: the first cobalt atom is coordinated by two sulfur atoms from different di­thiol­enes (bdt and tfd). The second cobalt atom is coordinated by one sulfur from one tfd and two olefinic carbons from another tfd. The third cobalt is coordinated by one sulfur from bdt and two sulfurs from tfd. This is, to the best of our knowledge, the first structurally characterized example of a molybdenum (tris­)di­thiol­ene complex that coordinates to cobalt. The F atoms of two of the –CF3 groups were refined as disordered over two sets of sites with ratios of refined occupancies of 0.703 (7):0.297 (7) and 0.72 (2):0.28 (2).

The conformations of the benzosuberone fused six- plus seven-membered ring fragments are very similar in each case, but the dihedral angles between the fused benzene ring and the pendant benzene ring differ somewhat, with values of 23.79 (3) for (I), 24.60 (4) for (II), 33.72 (4) for (III), 29.93 (8) for (IV) and 21.81 (7)° for (V). Key features of the packing include pairwise C—H⋯O hydrogen bonds for (II) and (IV), and pairwise C—H⋯N hydrogen bonds for (V), which generate inversion dimers in each case. The packing for (I) and (III) feature C—H⋯O hydrogen bonds, which lead to [010] and [100] chains, respectively. Weak C—H⋯π inter­actions consolidate the structures and weak aromatic π–π stacking is seen in (II) [centroid–centroid separation = 3.8414 (7) Å] and (III) [3.9475 (7) Å].

Crystal structure of a nickel compound comprising two nickel(II) complexes with different ligand environments: [Ni(tren)(H2O)2][Ni(H2O)6](SO4)2

The title compound, di­aqua­[tris­(2-amino­eth­yl)amine]­nickel(II) hexa­aqua­nickel(II) bis­(sulfate), [Ni(C6H18N4)(H2O)2][Ni(H2O)6](SO4)2 or [Ni(tren)(H2O)2][Ni(H2O)6](SO4)2, consists of two octa­hedral nickel complexes within the same unit cell. These metal complexes are formed from the reaction of [Ni(H2O)6](SO4) and the ligand tris­(2-amino­eth­yl)amine (tren). The crystals of the title compound are purple, different from those of the starting complex [Ni(H2O)6](SO4), which are turquoise. The reaction was performed both in a 1:1 and 1:2 metal–ligand molar ratio, always yielding the co-precipitation of the two types of crystals. The asymmetric unit of the title compound, which crystallizes in the space group Pnma, consists of two half NiII complexes and a sulfate counter-anion. The mononuclear cationic complex [Ni(tren)(H2O)2]2+ comprises an Ni ion, the tren ligand and two water mol­ecules, while the mononuclear complex [Ni(H2O)6]2+ consists of another Ni ion surrounded by six coordinated water mol­ecules. The [Ni(tren)(H2O)2] and [Ni(H2O)6] subunits are connected to the SO42− counter-anions through hydrogen bonding, thus consolidating the crystal structure.

In each compound, the metal ion is coordinated by the four secondary N atoms of the macrocyclic ligand, which adopts the most energetically stable trans-III conformation, and the mutually trans O atoms of the carboxyl­ate in a slightly tetra­gonally distorted trans-NiN4O2 octa­hedral coordination geometry. The crystals of both types of compounds are composed of parallel polymeric chains of the macrocyclic cations linked by the anions of the acid running along the [101] and [110] directions in I and II, respectively. In I, each polymeric chain is linked to four neighbouring ones by hydrogen bonding between the NH groups of the macrocycle and the carboxyl­ate O atoms, thus forming a three-dimensional supra­molecular network. In II, each polymeric chain contacts with only two neighbours, forming hydrogen bonds between the partially protonated carb­oxy­lic groups of the bridging ligand. As a result, a lamellar structure is formed with the layers oriented parallel to the (1overline{1}1) plane.

The cation is protonated at the meta-N atom (with respect to the carb­oxy group) in each case. In the crystal of (I), carb­oxy­lic acid inversion dimers linked by pairwise O—H⋯O hydrogen bonds are seen and each N—H group forms a hydrogen bond to a chloride ion to result in (100) undulating layers of chloride ions bridged by the inversion dimers into a three-dimensional network. The extended structure of (II) features O—H⋯Br, N—H⋯Br and N—H⋯O hydrogen bonds: the last of these generates C(7) chains of cations. Overall, the packing in (II) features undulating (100) sheets of bromide ions alternating with the organic cations. Inter­molecular inter­actions in the crystal of (III) include O—H⋯O, O—H⋯(O,O), N—H⋯O, N—H⋯N and O—H⋯N links. The cations are linked into (001) sheets, and the nitrate ions and water mol­ecules form undulating chains. Taken together, alternating (001) slabs of organic cations plus anions/water mol­ecules result. Hirshfeld surfaces and fingerprint plots were generated to give further insight into the inter­molecular inter­actions in these structures. The crystal used for the data collection of (II) was twinned by rotation about [100] in reciprocal space in a 0.4896 (15):0.5104 (15) ratio.

Comparing the backfilling of mesoporous titania thin films with hole conductors of different sizes sharing the same mass density

Efficient infiltration of a mesoporous titania matrix with conducting organic polymers or small molecules is one key challenge to overcome for hybrid photovoltaic devices. A quantitative analysis of the backfilling efficiency with time-of-flight grazing incidence small-angle neutron scattering (ToF-GISANS) and scanning electron microscopy (SEM) measurements is presented. Differences in the morphology due to the backfilling of mesoporous titania thin films are compared for the macromolecule poly[4,8-bis­(5-(2-ethyl­hexyl)­thio­phen-2-yl)benzo[1,2-b;4,5-b']di­thio­phene-2,6-diyl-alt-(4-(2-ethyl­hexyl)-3-fluoro­thieno[3,4-b]thio­phene-)-2-carboxyl­ate-2-6-diyl)] (PTB7-Th) and the heavy-element containing small molecule 2-pinacol­boronate-3-phenyl­phen­anthro[9,10-b]telluro­phene (PhenTe-BPinPh). Hence, a 1.7 times higher backfilling efficiency of almost 70% is achieved for the small molecule PhenTe-BPinPh compared with the polymer PTB7-Th despite sharing the same volumetric mass density. The precise characterization of structural changes due to backfilling reveals that the volumetric density of backfilled materials plays a minor role in obtaining good backfilling efficiencies and interfaces with large surface contact.

Three differently coloured polymorphs of 3,6-bis­(4-chloro­phenyl)-2,5-di­propyl-2,5-di­hydro­pyrrolo­[3,4-c]pyrrole-1,4-dione

In this paper, the conformational polymorphism of a chlorinated diketo­pyrrolo­pyrrole (DPP) dye having flexible substituents in a non-hydrogen-bonding system is reported. The propyl-substituted DPP derivative (PR3C) has three polymorphic forms, each showing a different colour (red, orange and yellow). All polymorphs could be obtained concomitantly under various crystallization conditions. The results of the crystal structure analysis indicate that PR3C adopts different conformations in each polymorph. The packing effect caused by the difference in the arrangement of neighbouring molecules was found to play an important role in the occurrence of the observed polymorphism. The thermodynamic stability relationship between the three polymorphs was identified by thermal analysis and indicates that the yellow polymorph is the thermally stable form. The results indicate that the yellow form and orange form are enantiotropically related, and the other polymorph is monotropically related to the others.

6 Ways College Might Look Different In The Fall

; Credit: /Hanna Barczyk for NPR

Elissa Nadworny | NPR

What will happen on college campuses in the fall? It's a big question for families, students and the schools themselves.

A lot of what happens depends on factors outside the control of individual schools: Will there be more testing? Contact tracing? Enough physical space for distancing? Will the coronavirus have a second wave? Will any given state allow campuses to reopen?

For all of these questions, it's really too early to know the answers. But one thing is clear: Life, and learning for the nation's 20 million students in higher education, will be different.

"I don't think there's any scenario under which it's business as usual on American college campuses in the fall," says Nicholas Christakis, a sociologist and physician at Yale University.

So why are so many colleges announcing they will be back on campus in the fall?

In many cases, it's because they're still trying to woo students. A survey of college presidents found their most pressing concern right now is summer and fall enrollment. Even elite schools, typically more stable when it comes to enrollment, have reportedly been tapping their waitlists.

In the midst of all this uncertainty, it's worth looking at some of the ideas out there. With the help of Joshua Kim and Edward J. Maloney, professors and authors of the book Learning Innovation and the Future of Higher Education, here are some potential scenarios for reopening colleges and universities:

All virtual

Perhaps the most obvious option for the fall is to continue doing what they've been doing this spring. Colleges have signaled that they're planning for this option — even if it's a last resort. California State University, Fullerton, was one of the first to announce publicly it was planning for a fall semester online.

"Obviously we want to resume in-person teaching as soon as possible, but we also need to make sure that we're safe," says Ellen Treanor, who helps lead strategic communication at the school. Treanor says it made a lot of sense to assume the school would start online. "What would be the easier way to transition? It would be easier to transition beginning virtually and then transitioning in person," she said. "The faculty [needs] to be prepared."

With virtual classes, students can remain at home, although some colleges are exploring bringing them back to campus, where they could use the school's Wi-Fi to take online classes.

Delayed start

A delay in the semester would allow a school to wait it out until it was safer to reopen. One option is to push back a month or two, starting in October or November. Another idea is to push a normal start to January. In that case, the spring semester would become the fall semester, and potentially students could stay on campus through next summer to make up the spring semester. Boston University floated a version of this January start date when it announced a number of plans it was exploring.

One downside to a late start is what students will do in the meantime, especially those who don't have financial stability and rely on campus or the university to be a safe and stable home.

Some online, some face-to-face

This would be a hybrid model, with a combination of virtual and in-person classes. It may be a good choice for campuses that don't have enough classrooms to allow adjusting face-to-face teaching to the requirements of social distancing.

"You might have some of the larger classes being taught online simply because it's harder to imagine a 150- or 350-person classroom," says Maloney, who leads the Center for New Designs in Learning and Scholarship at Georgetown University. "So you might see that class split up into multiple sections." For large, entry-level classes, colleges may have a lecture component online and then meet in smaller groups in person.

"The hybrid model doesn't have to just be about modality," Maloney says. "It can be, but it could also be about fundamentally rethinking what the core structure has been for those large classes."

Of course, shifting larger classes online may not be enough, by itself, to alleviate the health concerns of having students on campus. Early research from Cornell University found that eliminating such classes didn't lessen student interactions with each other.

Shortened blocks

In block scheduling, students take just one course at a time for a shorter duration, typically three or four weeks. Colorado College, a liberal arts school south of Denver, has been using this model for 50 years. The college adopted this style of classes because "it allows [students] to take a deep dive and really focus in unique ways on the single subject," says Alan Townsend, the provost there. In a typical year, the school offers eight blocks.

In addition to its intensity, block scheduling is attractive right now because it allows flexibility. Colleges that use it have the opportunity to change the way classes look every three weeks — since there are multiple start and stop points. (With a semester, you have only a single start and then, often 16 weeks later, an end.)

"It's easier for us to now think creatively for next year," Townsend says. "Different students can make different choices. That's really hard to do with a semester-based system, but the blocks allow us to do that a little bit more flexibly."

The school is also entertaining the idea of sending faculty abroad to teach a block for international students who might not be able to enter the U.S, or adding summer blocks to give students even more opportunities to take classes.

Only some on campus

Some colleges have suggested bringing only freshmen back to campus and having upperclassmen either delay their start, or be online and remote.

The idea centers on research that shows just how important a student's first year of college is as a predictor of graduation. Adapting to campus can be a challenge, so this would allow first-year students to get comfortable and have extra support on campus.

Since upperclassmen are already familiar with how campus and classes work, the theory goes, they can more easily adapt to an online environment. Other versions of this approach would have students who have housing needs come back to campus first, and then, over time, phase in other groups of students.

All these options seek to keep the population density of the campus lower while still maintaining some face-to-face interactions.

On campus, with some changes

Social distancing, improved testing and contact tracing could help colleges reopen their campuses.

"Every school is trying to figure out a way to have students come back and do whatever we can while also protecting public health," says Learning Innovation co-author Joshua Kim, director of online programs and strategy at Dartmouth College.

"At the same time, we know that, however that works, things will be different. It's probably unlikely that we'll be able to cram students together in large, packed lecture halls or put doubles and triples in residence halls or have big events."

To follow social distancing, professors are measuring their classrooms, calculating how many students could fit in the space if they were 6 feet apart. Deans are planning out how students could enter and exit the classrooms safely.

But it's not just the classrooms that pose a challenge. For residential colleges, it's the dorms.

"Whether or not students are actually learning in the classroom, it's incredibly important for them to have an on-campus experience," Maloney says. So schools are thinking about how they can spread their students out, putting them in places where they normally wouldn't go.

Some ideas include housing students in offices that aren't being used, local hotel rooms or off-campus housing. Institutions are also reimagining campus events, like freshman orientation, since it's unlikely hundreds of students will be in a packed auditorium.

"Rethinking how we do everything we do at a university is part of the process," Maloney says.

The Natura 2000 network is the backbone of nature conservation in the EU, and agri-environment schemes (AES) are an important tool to protect biodiversity on European farmland. A recent study, which investigated the effectiveness of AES in relation to grassland birds in Poland, found that AES were not associated with species richness of target species, and proposed a number of reasons for this. The researchers recommend that AES management regimes should be diversified and customised to provide optimal habitat for a wider range of bird species.
