Analytical and Spectroscopic Studies of New Mixed Ligand Complexes of 1,2-diamonobenzene

In the present investigation, we have synthesized Co(II) and Ni(II) mixed ligand complexes with 1,2-diaminobenzene. The complexes so obtained were characterized by conventional physico-chemical techniques, such as elemental analyses, solubility, electrical conductance, metal estimations, molecular weight determinations, infra red, electronic and ESR spectroscopy. These complexes were crystalline, coloured, solid, sparingly soluble in water and alcohol but soluble in DMF and DMSO, quite stable at room temperature. The magnetic and spectral studies confirm that the complexes are octahedral in nature.
