The present work has been designed for the characterization and antibacterial studies of mixed ligand complexes of Pd(II) ions with phthalic acid and heterocyclic amines. The general formula of the complexes is (MLL/) [where, M = Pd(II); L = Oxalic acid, C2O4, L/ = Quinoline, C9H7N(1); iso-Quinoline, C9H7N(2)]. The complexes were prepared in the solid form and characterized by elemental analysis, conductivity & magnetic measurements and infrared & electronic spectroscopic studies. The infrared spectra of the complexes confirmed the coordination of metal ion with ligands. Their antibacterial activity has been evaluated by the disc diffusion method against seven pathogenic bacteria (three gram positive and four gram negative). The complexes were shown to exhibit mild to moderate antibacterial activity against the tested bacteria.

A series of four mixed ligand complexes synthesized by reacting benzoylacetone and salicylaldehyde with different metal chlorides in ethanolic medium, were tested for their antimicrobial studies and indicated that the compounds are active against microorganisms used (Escherichia coli, Staphylococcus aureus, and Candida albicans) when compared with the activity of the reference or standard drugs (Erythromycin and Suptrin).Keywords: Antimicrobial, Synthesis, Ligands, Complexes

Diffusion Method

Mixed ligand complexes of Pd(II) and Pt(II) ions with phthalic acid and heterocyclic amines were synthesized and characterized. The general formula of the complexes is [MLL/]; where, M = Pd(II)(1-2), Pt(II)(3); L = phthalate, C8H4O4, L/ = pyridine, C5H5N(1); 2-aminopyridine, C5H6N2(2) and 4-picoline, C6H7N(3). The complexes were synthesized in the solid form and characterized by elemental analysis, electrical conductivity, magnetic measurements, and spectroscopic studies. Spectral analyses and magnetic measurements revealed the coordination of metal ion with ligands and geometry of the complexes. Anti-bacterial activity of the complexes against seven pathogenic bacteria (three gram positive and four gram negative) was assessed by the disc diffusion method. Complexes [Pd(Ph)(2-apy)] and [Pt(Ph)(4-pico)2] showed the highest anti-bacterial activity (when, Ph = bidentate phthalate, 2-apy = 2-aminopyridine and 4-pico = 4-picoline).

Biological Importance

pH-metric studies on the interaction of Ni(II), Zn(II) or Cd(II) with 1,10-phenanthroline (Phen) or 2,2′-bipyridyl (Bipy) in the presence of phenylalanine (Phe) indicate the formation of 1:1:1 mixed ligand chelates and their monohydroxo derivatives. The addition of Phe takes place after the combination of Phen or Bipy with the metal ion is complete. The formation constants of the resulting complexes have been determined at 30 ± 1 °C and ionic strength (µ) = 0.1 KNO3 and the ternary complexes involving Phen are found to be more stable than the corresponding complexes involving Bipy as primary ligand.
