Crystal structure characterization and electronic structure of a rare-earth-containing Zintl phase in the Yb–Al–Sb family: Yb3AlSb3

A rare-earth containing com­pound, Yb3AlSb3 (Ca3AlAs3-type structure), has been successfully synthesized within the Yb–Al–Sb system through flux methods. The crystal structure features infinite corner-sharing AlSb4 tetra­hedra, [AlSb2Sb2/2]6−, with Yb2+ cations residing between the tetra­hedra to provide charge balance.

Novel Ba2+ and Pb2+ metal–organic frameworks based on a semi-rigid tetra­carb­oxy­lic acid: syntheses, structures, topologies and luminescence properties

Two new main-group metal–organic frameworks (MOFs) based on the semi-rigid tetra­carb­oxy­lic acid 5,5′-methyl­enebis(2,4,6-tri­methyl­iso­phthalic acid) were prepared under hydro­thermal conditions and characterized. The Ba com­plex reveals a three-dimensional flu network formed via bridging tetra­nuclear SBUs, while the Pb com­plex displays a three-dimensional framework with an sqp topology based on one-dimensional metal chains. The luminescence properties of both com­plexes have also been investigated in the solid state.

Bis(2-nitro­phen­yl) selenide, bis­(2-amino­phen­yl) selenide and bis­(2-amino­phen­yl) telluride: structural and theoretical analysis

Theoretical and structural studies have been carried out on bis­(2-nitro­phen­yl) selenide, bis­(2-amino­phen­yl) selenide, and bis­(2-amino­phen­yl) telluride.

Synthesis, spectroscopic investigation, crystal structure analysis, quantum chemical study, biological activity and mol­ecular docking of three isatin derivatives

Three isatin derivatives were synthesized, crystallized by the slow-evaporation technique, characterized by 1H and 13C NMR spectroscopy, and analysed by the single-crystal X-ray diffraction (XRD) method. Quantum chemical parameters were calculated and the druglikeness and bioactivity scores of the com­pounds were predicted. The activities of these isatin derivatives against bacterial and fungal strains were determined using the well-diffusion assay method. Mol­ecular docking studies were carried out to predict the binding mode of the isatin com­pounds with the penicillin binding protein enzyme.
