A Novel Tripyridyldiamine Nickel Complex: Synthesis, Structure And Characterization

A novel nickel(II) complex [Ni(H(2)tpda)(NCS)(2)(CH3OH)] was synthesized by using tripyridyl-diamine 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 H(2)tpda, two NCS- ions and a ligand molecule CH3OH. The 3D supramolecular network is formed through hydrogen bonds and pi-pi interactions. The complex can catalyze the addition reaction of carbon dioxide and propylene oxide.
