When reacted in dry, degassed toluene, [Ir(COD)Cl]2 (COD = cyclo­octa-1,5-diene) and 2 equivalents of 2-(di-tert-butyl­phosphinito)anthra­quinone (tBuPOAQH) were found to form a unique tri-iridium compound consisting of one monoanionic dinuclear tri-μ-chlorido complex bearing one bidentate tBuPOAQ ligand per iridium, which was charge-balanced by an outer sphere [Ir(toluene)(COD)]+ ion, the structure of which has not previously been reported. This product, which is a toluene solvate, namely, (η2:η2-cyclo­octa-1,5-diene)(η6-toluene)­iridium(I) tri-μ-chlorido-bis­({3-[(di-tert-butyl­phosphan­yl)­oxy]-9,10-dioxoanthracen-2-yl}hydridoiridium(III)) toluene monosolvate, [Ir(C7H8)(C8H12)][Ir2H2(C22H24O3P)2Cl3]·C7H8 or [Ir(toluene)(COD)][Ir(κ-P,C-tBuPOAQ)(H)]2(μ-Cl)3]·toluene, formed as small orange platelets at room temperature, crystallizing in the triclinic space group Poverline{1}. The cation and anion are linked via weak C—H⋯O inter­actions. The stronger inter­molecular attractions are likely the offset parallel π–π inter­actions, which occur between the toluene ligands of pairs of inverted cations and between pairs of inverted anthra­quinone moieties, the latter of which are capped by toluene solvate mol­ecules, making for π-stacks of four mol­ecules each. The related ligand, 2-(di-tert-butyl­phosphinometh­yl)-anthra­quinone (tBuPCAQH), did not form crystals suitable for X-ray diffraction under analogous reaction conditions. However, when the reaction was conducted in chloro­form, yellow needles readily formed following addition of 1 atm of carbon monoxide. Diffraction studies revealed a neutral, dinuclear, di-μ-chlorido complex, di-μ-chlorido-bis­(carbon­yl{3-[(di-tert-butyl­phosphan­yl)­oxy]-9,10-dioxoanthracen-2-yl}hydridoiridium(I)), [Ir2H2(C23H26O2P)2Cl2(CO)2] or [Ir(κ-P,C-tBuPCAQ)(H)(CO)(μ-Cl)]2, Ir2C48H54Cl2O6P2, again crystallizing in space group Poverline{1}. Offset parallel π–π inter­actions between anthra­quinone groups of adjacent mol­ecules link the mol­ecules in one dimension.

A host–guest supra­molecular inclusion complex was obtained from the co-crystallization of A1/A2-bromo­but­oxy-hy­droxy difunctionalized pillar[5]arene (PilButBrOH) with adipo­nitrile (ADN), C47H53.18Br0.82O10·C6H8N2. The adipo­nitrile guest is stabilized within the electron-rich cavity of the pillar[5]arene host via multiple C—H⋯O and C—H⋯π inter­actions. Both functional groups on the macrocyclic rim are engaged in supra­molecular inter­actions with an adjacent inclusion complex via hydrogen-bonding (O—H⋯N or C—H⋯Br) inter­actions, resulting in the formation of a supra­molecular dimer in the crystal structure.

The mercury(II) halide complex [1,3-di-tert-butyl-2,4-bis­(tert-butyl­amino)-1,3,2λ5,4λ5-di­aza­diphosphetidine-2,4-diselone-κ2Se,Se']di­iodido­mercury(II) N,N-di­methyl­formamide monosolvate, [HgI2(C16H38N4P2Se2)]·C3H7NO or (1)HgI2, 2, containing cis-[(tBuNH)(Se)P(μ-NtBu)2P(Se)(NHtBu)] (1) was synthesized and structurally characterized. The crystal structure of 2 confirms the chelation of chalcogen donors to HgI2 with a natural bite angle of 112.95 (2)°. The coordination geometry around mercury is distorted tetra­hedral as indicated by the τ4 geometry index parameter (τ4 = 0.90). In the mercury complex, the exocyclic tert-butyl­amido substituents are arranged in an (endo, endo) fashion, whereas in the free ligand (1), the exocyclic substituents are arranged in an (exo, endo) pattern. Compound 2 displays non-classical N—H⋯O hydrogen-bonding inter­actions with the solvent N,N-di­methyl­formamide. These inter­actions may introduce geometrical distortion and deviation from an ideal geometry. An isostructural HgBr2 analogue containing cis-[(tBuNH)(S)P(μ-NtBu)2P(S)(NHtBu)] was also synthesized and structurally characterized, CIF data for the compound being presented as supporting information.

Two new zinc(II) complexes, tri­ethyl­ammonium di­chlorido­[2-(4-nitro­phen­yl)-4-phenyl­quinolin-8-olato]zinc(II), (C6H16N){Zn(C21H13N2O3)Cl2] (ZnOQ), and bis­(tri­ethyl­ammonium) {2,2'-[1,4-phenyl­enebis(nitrilo­methyl­idyne)]diphenolato}bis­[di­chlorido­zinc(II)], (C6H16N)2[Zn2(C20H14N2O2)Cl4] (ZnBS), were synthesized and their structures were determined using ESI–MS spectrometry, 1H NMR spectroscopy, and single-crystal X-ray diffraction. The results showed that the ligands 2-(4-nitro­phen­yl)-4-phenyl­quinolin-8-ol (HOQ) and N,N'-bis­(2-hy­droxy­benzyl­idene)benzene-1,4-di­amine (H2BS) were deprotonated by tri­ethyl-amine, forming the counter-ion Et3NH+, which inter­acts via an N—H⋯O hydrogen bond with the ligand. The ZnII atoms have a distorted trigonal–pyramidal (ZnOQ) and distorted tetra­hedral (ZnBS) geometries with a coord­ination number of four, coordinating with the ligands via N and O atoms. The N atoms coordinating with ZnII correspond to the heterocyclic nitro­gen for the HOQ ligand, while for the H2BS ligand, it is the nitro­gen of the imine (CH=N). The crystal packing of ZnOQ is characterized by C—H⋯π inter­actions, while that of ZnBS by C—H⋯Cl inter­actions. The emission spectra showed that ZnBS complex exhibits green fluorescence in the solid state with a small band-gap energy, and the ZnOQ complex does exhibit non-fluorescence.

Analysis of small-angle scattering (SAS) data requires intensive modeling to infer and characterize the structures present in a sample. This iterative improvement of models is a time-consuming process. Presented here is Scattering Equation Builder (SEB), a C++ library that derives exact analytic expressions for the form factors of complex composite structures. The user writes a small program that specifies how the sub-units should be linked to form a composite structure and calls SEB to obtain an expression for the form factor. SEB supports e.g. Gaussian polymer chains and loops, thin rods and circles, solid spheres, spherical shells and cylinders, and many different options for how these can be linked together. The formalism behind SEB is presented and simple case studies are given, such as block copolymers with different types of linkage, as well as more complex examples, such as a random walk model of 100 linked sub-units, dendrimers, polymers and rods attached to the surfaces of geometric objects, and finally the scattering from a linear chain of five stars, where each star is built up of four diblock copolymers. These examples illustrate how SEB can be used to develop complex models and hence reduce the cost of analyzing SAS data.

Financial literacy in Singapore has not been analysed in much detail, despite the fact that this is one of the world’s most rapidly aging nations. In this podcast, Professor of Finance Benedict Koh from the SMU Lee Kong Chian School of Business, discusses the key findings of his research jointly conducted with Olivia Mitchell from the University of Pennsylvania and Susann Rohwedder, Senior Economist at the RAND Corporation and Associate Director of the RAND Center for the Study of Aging. Using a unique new data-set and nationally representative survey - the Singapore Life Panel, they conducted an analysis of older Singaporeans’ financial literacy. Here, Professor Koh discusses his key findings, including: Do older Singaporeans score better on financial knowledge compared to their counterparts in the United States? What are the empirical linkages between financial literacy and retirement preparedness in Singapore? And is financial literacy positively associated with greater wealth and diversity of portfolios?

There is little in our lives that does not rely on software. That has been the reality for quite some time, and it will be even more true as self-driving cars and similar technologies become an even greater part of our lives. But as our reliance on software grows, so does the potential for disaster as software becomes increasingly complex.

In September 2017 The Atlantic magazine featured “The Coming Software Apocalypse,” an article by James Somers, that offers a fascinating and sobering look at how rampant code complexity has caused massive failures in critical software systems, like the 2014 incident that left the entire state of Washington without 911 emergency call-in services until the problem was traced to software running on a server in Colorado.

One of the people interviewed in that Atlantic article was Chris Newcombe, an expert in dealing with software complexity. Chris, an architect on the Oracle Bare Metal infrastructure as a service team,  is one of the panelists for the discussion you are about to hear. Chris is joined by Java Champion and microservices expert Chris Richardson, Java Champion Adam Bein, and Oracle ACE Director and Developer Champion Lucas Jellema. The conversation focuses on what developers can do to combat complexity.

In a 5-month period beginning in late 2018, two Boeing 737 Max aircraft crashed in similar circumstances, killing 343 people. Investigators determined that in each case the crash was caused by problems with flight control software unique to that aircraft model. All 737 Max aircraft were subsequently grounded, where they remain, and the story remains in the news. This podcast, a rebroadcast of a show published on March 21, 2018, looks at the increasing complexity in software, and at what can be done to reduce that complexity and increase safety.
