The M(II) complex of benzofuron-2-carbohydrazide, 1-chloro-4-isothiocyanatobenzene and nitrophenol (2-nitrophenol, 2,3- dinitropheno, 2,3,4- trinitrophenol) with transition metal ion e.g. Cu(II), Ni(II) and Co(II) were prepared. All the complex have structure formula [Cu2(C56H40N10Cl2O16S2)], [Ni2 (C56H40N10Cl2O16S2)], [Co2 (C56H40N10Cl2O16S2)], [Cu2 (C56H36N14 Cl2O24S2)], [Ni2 (C56H36N14Cl2O24S2)], [Co2 (C56H36N14Cl2O24S2)], [Cu2 (C56H32N18Cl2O32S2)], [Ni2 (C56H32N18Cl2O32S2)] and [Co2 (C56H32N18Cl2O32S2)] characterized by the several analytical techniques including elemental analysis (C.H.N.), molar conductance measurements, magnetic measurements, electronic, FAB mass, IR, 1H NMR and 13C NMR spectral studies. Based on these studies six coordinated octahedral geometry for all the complexes was proposed.
