Synthesis and Characterization of Some Transition Metal Complexes Derived from 4-Hydroxy Coumarin and 4-Aminophenol

Abstract

Metal(II) complexes of the type ML₂·nB [Mn(II), Co(II), Ni(II) and Cu(II), L = Schiff base derived from 3-formyl-4-hydroxy coumarin and 4-aminophenol, B = H₂O, n = 0….] have been prepared and characterized by elemental analysis, molar conductance, IR, electronic and magnetic susceptibility studies. Molar conductivity measurements indicate that the complexes are non-electrolytic in nature. The analytical data indicate that the metal to ligand ratio in all complexes is 1:2. IR spectra show that the Schiff base behaves as a bidentate ON donor system.
