Mixed ligands of 2-acetamide benzothiazole L1 with 1,10-phenanthrolin L2complexesof V(IV), Cr(III) , Co(II)and Ni(II )ions were prepared by microwave assisted radiation. The ligand and the complexes were isolated and characterized in solid state by using FT-IR, UV-Vis spectroscopy, flame atomic absorption, elemental analysis CHNS , magnetic susceptibility , melting points and conductivity measurements.2-acetamide benzothiazole behaves as bidenetate through carbonyl group and nitrogen atom of imine group. Fromthe analyses Oh geometry was suggested for NiL1L2, CrL1L2 complexes, square pyramidal for VL1L2 and Td for CoL1L2complex.A theoretical treatment of ligands and their metal complexes in gas phase were studied using HyperChem-8 program, moreover, ligands in gas phase also has been studied using Gaussian program (GaussView Currently Available Version (5.0.9) along with Gaussian 09 which was the latest in the Gaussian series of programs).
