Synthesis, Crystal Structure and Thermal Studies of bis(O,O′‐Dibenzyldithiophosphato)‐(2,2′‐Bipyridine)nickel(II) Complex

Abstract

Abstract The bis(O,O′‐dibenzyldithiophosphato)Ni(II) adduct, [(PhCH2O)2PS2]2Ni(bpy), was synthesized by the reaction of [(PhCH2O)2PS2]2Ni with 2,2′‐bipyridine in the solid state. Single crystals of the title compound as the dihydrate were obtained by recrystallization in ethanol–distilled water (v/v = 9:1). The structure characterization was performed by means of IR, elemental analyses, and single crystal x‐ray analysis. The crystal of the title compound consists of two disconnected structural units, each of which includes two non‐coordination water molecules. The coordination geometry of each Ni atom is a distorted octahedron. The thermogravimetric (TG) data indicate that thermal decomposition of the title compound takes place in four steps and the residue is Ni(OPS2)2.
