| Abstract : A new ligand 1E,2E- ethanedial (2,4-dinitro phenyl) hydrazone [5-(2-hydroxy phenyl)-1,3,4-oxadiazol- 2-yl] hydrazone (L) and its Cr (III), Fe (III), Co (III), Ni (II) and Cu (II) complexes were synthesized . The authenticity of the ligand and its transition metal complexes were established by elemental analyses, conductance measurements, as well as spectroscopy (IR, mass, uv-visible). The IR and mass spectral studies was corresponding as it is expected. The electronic spectral studies suggest an octahedral geometry for the complexes [Cr (III), Fe (III), Co(III)] and tetrahedral geometry for the complex Ni (II) and Cu (II) The ligand acts as a tridentate ligand coordinating through the oxygen atom of the oxadiazole ring and as well through the two nitrogen. | ||
