Abstract: The Manganese (II), Nickel (II) and Zinc (II) complexes of Uramido Benzoic acid were prepared and characterized by magnetic studies, molar conductance studies, thermal analysis and spectroscopic techniques (FTIR and UV). The IR spectral studies revealed that the Uramido Benzoic acid behaves as a tridentate ligand. Electronic spectral studies and magnetic studies suggest that the complexes are in octahedral geometry. The thermal study explained the stability of complexes and their decomposition.
