Synthesis and characterization of new transition metal complexes of heterocyclic sulfur-containing Schiff base

New bis-chelated Ni(Ⅱ) complexes with schiff base ligands derived from S-benzyldithiocarbazate and 1-(2-Pyrazinyl)ethanone were prepared.The compounds were characterized by elementary analysis, IR spectra, electronic spectra and molar conductance measurements,Its coordination geometry is suggested to be close to octahedron or distorted octahedron,Its coordination geometry is suggested to be close to octahedron or distorted octaheron.
