Synthesis, Characterization, and Antibacterial effect of Complexes lead(II) and Tin (II) With (L-leucin and 8-hydroxyquinoline)

Abstract

The research includes the synthesis and identification of two types complexes of M+2 Ions using amino acid(
L-leucin) and 8-hydroxyqinoline as ligands in general compositions [ M (Leu)2] and
[ M (Q)2] were L-leucin (C6H13NO2)symbolized as (LeuH), and 8-hydroxyqinoline,(C9H7NO2) symbolized as
(8-HQ) ,M(II) =Sn(II) and Pb(II), The ligand and metal ions were brought into reaction in ethanolic medium
using (1:2) metal : ligand molar ratios as required.
Products were found to be solid crystalline complexes, which have been Characterized through the
following techniques: Melting points, Solubility, Molar conductivity. Determination the percentage of the
metal in the complexes by (Atomic Absorption Spectrometry). chloride ion content were also evolution by
(mohr method) . Spectroscopic Methods [FT-IR and UV-Vis]. The proposed structure of the complexes using
program , chem office 3D(2006)
