Abstract

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.
