The crystal and molecular structures of [Ni(Im)6](dtp)2 (Im = imidazole, dtp = O,OÃ¢Â€Â²-diphenyldithiophosphate) have been determined by X-ray crystallography. It crystallizes in the triclinic system, space group PÃ„Â«, with cell parameters a = 9.375 (2), b = 12.324(3), c = 13.285(3) ÃƒÂ…, ÃŽÂ± = 107.86(3), ÃŽÂ² = 102.28(3), ÃŽÂ³ = 109.24(3), and Z = 1. The crystal structure of the title compound is built up of discrete monomeric molecules of [Ni(Im)6](dtp)2. The nickel (II) ion is hexacoordinated by six imidazole molecules and the coordination environment of Ni (II) is of octahedral geometry. In the solid state, a network of N-HÃ‚Â·Ã‚Â·Ã‚Â·S intermolecular hydrogen bonds connect the Ni(Im)6 moieties and O,OÃ¢Â€Â²-diphenyldithiophosphate molecules, forming a three-dimensional structure.
