Abstract
Novel three mixed ligand complexes derived from the interaction of Cr(III), Fe(III) and La(III) ions with a Schiff base resulted from the condensation process of 2-aminophenol and 2-hydroxy acetophenone(HL1) as a primary ligand (HL1) and anthranilic acid (L2) as a secondary ligand. The formed mixed ligand complexes were synthesized and characterized using elemental analysis, FTIR, 1HNMR, UV–visible and mass spectroscopy as well as molar conductance and magnetic measurements. The obtained results revealed that the mixed ligand complexes were formed in 1:1:1[L1ML2] ratio and non-electrolytic in nature.
Highlights
The Schiff bases were first synthesized by Hugo Schiffs (German chemist) in 1864, by the reaction of organic compounds containing carbonyl group(C=O); aldehydes or ketones with primary amines or amino acids in the presence or absence of bases, acids in organic solvents [1]
The antibacterial activity of mixed ligand chelates were tested against five pathogenic bacteria species, like Staphylococcus aureus and Enterococcus faecalis, Pseudomonas aeruginosa, Klebsiella sp. and Escherichia coli using the agar well diffusion assay Maihub, et al [9]
This work aims to establish the geometrical structure of Cr(III), Fe(III) and La(III) mixed ligand complexes resulted from the reaction of Schiff base[2-hydroxyacetophenone with 2-aminophenol] as primary ligand and anthranilic acid as secondary ligand
Summary
The Schiff bases were first synthesized by Hugo Schiffs (German chemist) in 1864, by the reaction of organic compounds containing carbonyl group(C=O); aldehydes or ketones with primary amines or amino acids in the presence or absence of bases, acids in organic solvents [1]. They releaved many applications such as in chemistry and medicine. Prepared and investigated some mixed ligand chelates. The antibacterial activity of mixed ligand chelates were tested against five pathogenic bacteria species, like Staphylococcus aureus and Enterococcus faecalis, Pseudomonas aeruginosa, Klebsiella sp. Prepared and characterized some mixed ligand complexes of benzoin and phathalic acid
