The bis(O,O′-dibenzyldithiophosphato)Ni(II) adduct, [(PhCH ₂O)₂PS₂]₂ Ni(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.
