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.

Abstract

A novel Mn(II) complex with thiosemicarbazone derived from 2-acetylpyridine and N(4)-ethylthiosemicarbazide has been prepared. The single-crystal X-ray analysis of the Mn(II) complex showed a distorted octahedral MnN4S2 environment with the ligand chelating via the nitrogen and sulfur donor atoms in a tridentate manner. The triclinic form of the ligand which has crystallized in a monoclinic system in other works is also described. The basicity of nitrogen atoms of the ligand was tested with its reaction with HNO3 and the structure of the salt obtained is reported. The result shows that the lone pair of the pyridine nitrogen is more available due to the delocalization of other nitrogen lone pair of electron.
