“…While NO 2 pesesiH ligand has moderate activity against S. aureus and P. aeruginosa, OMepesesiH ligand against these bacteria has weak activity. Considerable activity of Schiff base ligands may be arisen from the presense of imine group which imports in elucidating the mechanism of transformation reaction in biological system and also from the presense of the hydroxyl and N-pyridyl groups, which may play an important role in the antibacterial activity [2, [21][22][23]. BrpesesiH ligand was found to be the most potent antibacterial agent, indicating that bromine atom played an important role in the antibacterial activity [2].…”

“…The other Schiff bases show variable activities. The significant activities of the Schiff bases may arise from the presence of imine, hydroxyl, and pyridyl-N functional groups [36][37][38]. pythsalHI was the most potent antibacterial agent, indicating that the iodine plays an important role in the antibacterial activity [34,35].…”

The synthesis and characterization is reported of four iron(III) complexes of general formula [Fe(pythsalX)-(H 2 O) 2 ]Cl 2 , derived from the NSNO-donor tetradentate Schiff base ligands pythsalHX ([5-X-N-(2-pyridylethylsulfanylethyl)salicylideneimine] (X = OMe, N 2 Ph, I, NO 2 ). The complexes were characterized by physico-chemical and spectroscopic methods. The thermal stabilities of both the free Schiff bases and their complexes were studied by differential scanning calorimetry and thermogravimetric analyses. The spectroscopic data suggest that the Schiff base ligands coordinate through deprotonated phenolic oxygen, imine, and pyridine-type nitrogens and the thioether sulfur atoms to give an octahedral geometry around the iron(III) atom in all these complexes. The free Schiff bases and their complexes have been screened for antimicrobial activities and the results show that the free Schiff bases are more potent antibacterials than the complexes.

“…spectra of the free ligands and their metal complexes were recorded in DMSO-d 6 . The spectra of the ligands L 1 H and L 2 H exhibit a broad signal due to the NH proton, which is absent for the [M(L) 2 ] complexes.…”

“…The coordination complexes of sulphur and nitrogen donor ligands have been widely investigated and they frequently show novel structural features [4], unusual spectral and catalytical properties [5] and relevance to biological systems [6]. The metal complexes of thiosemicarbazones and semicarbazones have aroused considerable interest in view of their industrial and biological applications [7].…”

The monobasic bidentate Schiff base complexes of palladium(II) and platinum(II) derived from 1H-indol-2,3-dione thiosemicarbazone (L 1 H) and 1H-indol-2,3-dione semicarbazone (L 2 H) have been characterized on the basis of elemental analysis, molecular weight determinations, i.r., 1 H n.m.r. and u.v. spectral studies. Based on these studies a square planar environment around the metal atoms has been proposed. Antimicrobial effects of both the ligands and their complexes on different species of pathogenic fungi and bacteria have been recorded and these are found to possess significant fungicidal and bactericidal properties.
