Abstract

New metal complexes derived from the reaction of N-benzoyl-N′-carboxyl methylthiopropylidine thiourea (BCMT) with Cu(II), Co(II), Ni(II), and Fe(III) chloride and/or acetate salts have been synthesized and characterized using elemental analyses, molar conductance, spectral (IR, UV-Vis., mass, 1H NMR), thermal (TGA, DTG), and magnetic measurements. The IR results showed the modes of coordination in case of mononuclear and binuclear metal complexes. Different types of geometries are suggested on the basis of the spectral and the magnetic data. Also, the ligand field parameters for the metal complexes were calculated. The amounts of the solvents as well as the mechanism of decomposition were proposed using thermal measurements. The results of biological activity of the ligand give us the promise to be effective in tumors treatment.
