Synthesis and crystal structure of nickel(II) complexes with bis(5-methyl-2-thiophenemethyl)(2-pyridylmethyl)amine

Abstract

A series of nickel(II) complexes having the (Me-Tp)2PMA ligand ((Me-Tp)2PMA = bis(5-methyl-2-thiophenemethyl)(2-pyridylmethyl)amine) with nitrates (1), chlorides (2), and perchlorates (3) as anions were synthesized and isolated. All these complexes were successfully characterized by physicochemical methods including X-ray crystallographic analysis. In complex 1, the ligand binds in a bidentate N2 fashion, whereas in the cases of 2 and 3 the ligand binds in the tridentate N2S form. The coordination geometry around the nickel(II) atoms in these complexes is distorted octahedral. © 2009 Elsevier Ltd. All rights reserved.
