In an effort to isolate the 16-vertex supraicosahedral cobaltaborane [(Cp*Co)BHCo{Cp*CoBH}] (Cp* = η-CMe), we have pyrolyzed an in situ generated intermediate, obtained from the fast metathesis of [Cp*CoCl] and [LiBH·THF], with an excess amount of [BH·THF]. Although the objective of isolating the 16-vertex cobalt analogue was not achieved, the reaction yielded a closo-19-vertex face-fused cluster presenting icosahedral {CoB}, tetrahedral {B}, and 10-vertex {CoB} units. The reaction also yielded a 20-vertex face-fused cluster that contains icosahedral {CoB}, square-pyramidal {CoB}, tetrahedral {CoB}, and nido-{CoB} units.

A twofold interpenetrated three-dimensional barium(II) metal-organic framework constructed from 2,2'-[terephthaloylbis(azanediyl)]diacetate: synthesis, structure, dihydrogen bonding and spectroscopic properties.

A new twofold interpenetrated 3D metal-organic framework (MOF), namely, poly[[μ-aqua-diaqua{μ-2,2'-[terephthaloylbis(azanediyl)]diacetato}barium(II)] dihydrate], {[Ba(CHNO)(HO)]·2HO}, (I), has been assembled through a combination of the reaction of 2,2'-[terephthaloylbis(azanediyl)]diacetic acid (TPBA, HL) with barium hydroxide and crystallization at low temperature. In the crystal structure of (I), the nine-coordinated Ba ions are bridged by two μ-aqua ligands and two carboxylate μ-O atoms to form a 1D loop-like Ba-O chain, which, together with the other two coordinated water molecules and μ-carboxylate groups, produces a rod-like secondary building unit (SBU). The resultant 1D polynuclear SBUs are further extended into a 3D MOF via the terephthalamide moiety of the ligand as a spacer.

Divergent synthesis of valuable molecules through common starting materials and metal catalysis represents a longstanding challenge and a significant research goal. We here describe chemodivergent, highly enantio- and regioselective nickel-catalyzed reductive and dehydrogenative coupling reactions of alkynes, aldehydes, and silanes. A single chiral Ni-based catalyst is leveraged to directly prepare three distinct enantioenriched products (silyl-protected trisubstituted chiral allylic alcohols, oxasilacyclopentenes, and silicon-stereogenic oxasilacyclopentenes) in a single chemical operation.

Background: C-reactive protein (CRP) is a prognostic biomarker for clear cell renal cell carcinoma (ccRCC). However, there may be potential racial heterogeneity in distribution and prognostic impact of CRP level. We investigated potential racial differences in distribution and prognostic impact of preoperative CRP among Asian (AS), African American (AA), and Caucasian (CAUC) patients with non-metastatic ccRCC (nmccRCC).

Food freshness monitoring and volatile amine detection are key to food safety. In this study, we demonstrated the applicability of mixed-valence rhenium oxide quantum dots (MV-ReOQDs), synthesized via the hydrothermal reaction of α-cyclodextrin and rhenium ion precursors, in triethylamine (TEA) sensing. Spectroscopic correlation techniques showed that the developed MV-ReOQDs possessed mixed-valent rhenium, α-cyclodextrin as capped ligand, partially carbonized surface, and amorphous phase structure.
