Synthesis, spectroscopic characterization and antibacterial activity of mixed ligand complexes of Cr (III)‎,Fe (III)‎, and La (III)‎ with nitroso-2-naphthol and l-leucine-1

الملخص EN

The mixed ligand complexes of Cr (III),Fe (III) and La (III) with 1-nitroso-2-naphthol (C10H7NO2), symbolized (NNPhH) ] and amino acid [ L-leucine (C6H13NO2), symbolized (Leu H), were synthesized and characterized by : Melting points, Solubility, Molar conductivity.

determination the percentage of the metal in the complexes by flame(AAS), magnetic susceptibility measurements, chloride ion content.

Spectroscopic Method [FT-IR and UV-Vis], and Program [Chem office–CS.

Chem.

– 3D pro 2004] was used. The results showed that the deprotonated tow 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.

Octahedral geometry for Cr (III), Fe (III), and La (III) are proposed.
