SYNTHESIS AND CHARACTERIZATION OF SOME COMPLEXES DERIVED FROM 3-AZOMETHINE-2-METHYL-BENZOPYRROLE DERIVATIVES

The reaction of 3-azomethine-2-methyl-benzopyrrole derivatives (L,L' or L'') with some hydrated metal salt of Mn(II), Fe(III), Co(II), Ni(II) and Cu(II) affords complexes having the composition [MLCl(CH2O)]nH2O (M=Mn(II), Co(II), Ni(II) or Cu(II), n = 0,1), [FeLCl2(OC2H6)2]H2O, [ML2]nH2O (M=Mn(II) or Co(II), n = 1 or 2), [FeL'Cl2(H2O)2]H2O, [NiL'HCl2]H2O, [CuL2Cl2], [ML''HCL2]nH2O (M=Mn(II) or Ni(II) or Ni(II), n = 2,0), [ML''ClH2O]nH2O (M = Co(II) or Cu(II), n = 3,1) and [FeL''Cl2H2O]H2O where the symbol L,L' and L'' refers to the ionized ligand LH , L'H and L''H. The complexes are characterized by elemental analyses, molar conductivities, magnetic measurements, uv, visible, ir and esr spectral data.
