Bis(1,3-Benzothia-zole-2-Thiol-ato)[(Z)-Methyl 2-(2-Amino-1,3-Thia-zol-4-yl)-2-(Methoxy-imino)Acetate]Nickel(II)

Abstract

In the title compound, [Ni(C<inf>7</inf>H<inf>4</inf>NS<inf>2</inf>) <inf>2</inf>(C<inf>7</inf>H<inf>9</inf>N<inf>3</inf>O<inf>3</inf>S)], the NiII ion is in a slightly distorted N4S2 octa-hedral coordination environment. The two benzothia-zole-2-thiol-ate ligands chelate via their thia-zole N and thiol-ate S atoms while the methyl 2-(2-amino-thia-zol-4-yl)-2- (methoxy-imino)acetate also acts as a chelate ligand binding through the thia-zole and imino N atoms. Intra-molecular N - H⋯N, C - H⋯N and C - H⋯O interactions contribute to the molecular conformation. In the crystal structure, intermolecular N - H⋯O hydrogen bonds produce R <inf>1</inf> 2(6) rings and generate chains along the c axis. An extensive one-dimensional supra-molecular network of N - H⋯O hydrogen bonds and C - H⋯π interactions is responsible for the crystal structure stabilization. © 2010.
