Synthesis and characterization of mixed ligand complexes of some metals with 1-nitroso-2-naphthol and L-leucin

Abstract

The mixed ligand complexes of Mn(II),Fe(II),Co(II),Cd(II), and Pb(II) with 1- nitroso-2- naphthol (C10H7NO2), symbolized (NNPhH)] and amino acid [L-leucin (C6H13NO2), symbolized (LeuH), were synthesized and characterized by: Melting points, Solubility, Molar conductivity, and determination the percentage of the metal in the complexes by flame(AAS), magnetic susceptipibility , Spectroscopic Method [FT-IR and UV-Vis], And Program [Chem office– CS.Chem.– 3D pro 2004] was used. The results showed that the deprotonated two ligands acts as a bidentate ligand , (leu-) was coordinated to the metal ions through the oxygen of the carboxylic group and the nitrogen of the amine and the 1-nitroso-2-naphthol ligand was coordinated to the metal ions through the oxygen and nitrogen atoms . Octahedral geometry for M(II) are proposed.
