A Novel Tripyridyldiamine Nickel Complex:Synthesis,Structure and Characterization

A novel nickel(II)complex[Ni(H2 tpda)(NCS)2(CH3 OH)]was synthesized by using tripyridyldiamine as ligand and Ni(NCS)2 as starting materials,and characterized by a variety of techniques including single-crystal X-ray diffraction,IR spectroscopy and TG-DSC.The single-crystal structure reveals that the complex exhibits as a neutral molecule and that the central atom Ni(II)is octahedrally coordinated by an H2 tpda,two NCS-ions and a ligand molecule CH3 OH.The 3 D supramolecular network is formed through hydrogen bonds andπ-πinteractions.The complex can catalyze the addition reaction of carbon dioxide and propylene oxide.
