Abstract: The chemistry of 1,1’-bis(ortho-carborane) has rapidly developed in recent years since a convenient method was reported for its synthesis. Here we review the recent progress in this field with main emphasis on the synthesis of 1,1’-bis(carborane)- based transition metal complexes and heterocycles.

Abstract:  Two new zinc coordination polymers based on N-[(3-Pyridine)-sulfonyl]amino acid ligand have been synthesized and characterized by single-crystal X-ray diffraction and elemental analysis. The results show that the 1 is a two-dimensional structure coordination polymer and synthesized under room temperature condition; the 2 is a three-dimensional structure coordination polymer and synthesized under hydrothermal synthesis condition. These two structures are formed by 4,4′-dipyridy and 4,4′-azpy for 1 and 2, respectively. A structural comparison of these two coordination polymers suggests that different reaction temperatures play important role in the construction of resulting architectures of 1 and 2. Fluorescence measurements show that 1 has medium fluorescent emission at 374 nm and 2 has medium fluorescent emission at 438 nm.

Abstract: Two new cyclohexyltin N-(salicylidene)valinates, [2-HOC6H4CH=NCH(CH(CH3)2)COO]SnCy3 (1) and [2-OC6H4CH=NCH(CH(CH3)2)COO]SnCy2 (2) (Cy = cyclohexyl), have been synthesized and characterized by elemental analysis, IR, and 1H NMR. The crystal structure of 2 has been determined by X-ray single crystal diffraction. In the complexes, the carboxylate is monodentate. Complex 1 is a four-coordinated tin compound, and 2 has a distorted trigonal bipyramidal geometry with the axial locations occupied by one carboxylate oxygen and a phenolic oxygen of the ligand. Bioassay results show that 1 and 2 have good in vitro antibacterial activity against Escherichia coli.
