Ligation properties of 2-acetyl-2-thiazoline semicarbazone (ATsc): Isolation, spectroscopic and X-ray study of ATsc and its Cu(II) and Ni(II) complexes

A new Schiff base ligand 2-acetyl-2-thiazoline semicarbazone (ATsc) and its copper(II) and nickel(II) complexes were synthesized and characterized by physical measurements. The X-ray crystal structures of ATsc, its copper complex and its nickel complex have also been determined. The geometry around the metallic atoms can be described as a distorted square-pyramid for the copper complex and as a distorted octahedron for the nickel complex.
