Abstract

Metal complexes of Cr(III), Mn(II) of the Schiff base derived from (E)-1-((3-aminophenyl)imino)methyl)naphthalene-2-ol have been prepared and characterized on the basis of physical characteristics, micro-analytical data(CHN), molar conductivity, magnetic moment measurements, Mass spectra, 1HNMR, IR and UV-Vis spectrum data. The elemental analysis data showed the isolated complexes are in 1:1 [M:L] ratio .The obtained molar conductance values revealed the complexes  are nonelectrolyte in nature. The results of magnetic moment measurements showed that, the complexes of Cr(III), Mn(II), have unpaired electrons. The infrared spectral data displayed the main coordination sites of  (E)-1-((3-aminophenyl)imino) methyl)naphthalene-2-ol    towards Cr(III), Mn(II) ions. The electronic spectral results of the Schiff base ligand and its complexes suggest that, the Cr(III), Mn(II) complexes have octahedral and tetrahedral structure.
