Abstract: Syntheses of complexes of a few first transition series bivalent metal ions like Co(II), Ni(II) and Cu(II) complexes with 2-benzimidazolyl mercaptoaceto hydrazone have been reported. The complexes have been characterized on the basis of analytical, molar conductivity, magnetic susceptibilities, infrared, electronic, X-ray diffraction (powder) and ESR spectral data. Infrared spectral data show that the ligands behave in a monobasic tridentate manner in all the complexes except in Cu(II) complexes, where they act as dibasic tridentate ligands with ONO donor sequence. Co(II) and Ni(II) complexes have octahedral geometry, while Cu(II) complexes have square planar geometry. The thermal stabilities of the complexes have been studied by TGA. The kinetic parameters has also been calculated.
