The ligand 2-amino acetic acid -6- methoxy benzothiazole (L) was prepared as a chelating ligand, which was treated with the ions Rh(III), Pd(II), Cd(II) and Pt(IV) in alcoholic medium in order to prepare series of new metal complexes. These complexes were prepared by conventional and microwave methods and characterized by the available techniques. FT-IR, UV-Visible, magnetic susceptibility, flame atomic absorption technique as well as elemental analysis and coductivity measurements. From the spectral studies, all complexes have square planer geometry except Cd complex have Td geometry. The nature of complexes in liquid state was studied by using molar ratio method and give results similar approximately to those obtained from isolated solid state; also, stability constant of the prepared complexes were studied and found that they were stable in molar ratio 1:1. A theoretical treatment of these compounds in gas phase was studied by Hyper Chem-8 program using Semi-empirical method.
