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.

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.
