ABSTRACT Mononuclear copper(II) complex [CuLCl2] where L = (2-methylsulfanyl-phenyl)-(phenyl-pyridin-2-yl-methylene)amine, a tridentate NNS donor Schiff base ligand has been synthesized and characterized by microanalysis, IR, UV-Visible spectra and magnetic studies. Crystal structure of the complex has been solved by single crystal X-ray diffraction studies and shows the complex has distorted trigonal bipyramidal geometry.

Key words. Copper(II); NNS donor ligand; five coordinate; IR; structure.

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 heterocycles and transition metal complexes as well as metallacarboranes.

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.
