“…This band disappears in their corresponding metal complexes indicating the coordination of carboxylic oxygen to metal ion through deprotonation. The asymmetrical and symmetrical vibration of υ(COO − ) were noticed in the spectrum of the ligand at 1655 and [34] The Schiff base exhibits signals at 4.49 and 10.99 ppm due to OH and NH protons, respectively. It also exhibits resonance due to -CH 2 -protons around 2.74 ppm.…”

A new Azo-Schiff base ligand L was prepared by reaction of m-hydroxy benzoic acid with (Schiff base B) of 3-[2-(1H-indol-3-yl)-ethylimino]-1.5-dimethyl-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylamine. This synthesized ligand was used for complexation with different metal ions like Ni(II), Co(II), Pd(II) and Pt(IV) by using a molar ratio of ligand: metal as 1:1. Resulted compounds were characterized by NMR ( 1 H and 13 C), UV-vis spectroscopy, TGA, FT-IR, MS, elemental analysis, magnetic moment and molar conductivity studies. The activation thermodynamic parameters, such as ΔE*, ΔH * , ΔS * , ΔG * and K are calculated from the TGA curves using Coats-Redfern method. Hyper Chem-8 program has been used to predict structural geometries of compounds in gas phase. The biological activities of Schiff base and its complexes had been tested in vitro against, two Gram positive bacteria (Bacillus subtillis and Staphylococcus aureus) and two Gram negative bacteria (Escherichia coli and Pseudomonas aeruguinosa).

“…The absorptions at 261 and 325 nm represent π → π* transitions of the aromatic ring and the bands at 378 and 406 nm can be assigned as n → π* transitions for imine of the azomethine groups of L 1 . The oligomeric ligand L 2 shows quite similar absorption values to those of the monomeric form showing bands at 252–286 nm for the aromatic ring and 356 nm of n → π* transition for the imine group …”

,g Naringenin-based Schiff base ligands with 4-aminobenzoic hydrazide were obtained as a unilateral form (L 1 ). The ligand was oligomerized by oxidative polycondensation reaction with NaOCl as an oxidant in an aqueous alkaline medium at 90°C to form a functional oligomer (L 2 ), and its transition metal complexes such as those with Cu(II), Ni(II) and Zn(II) were prepared. The monomer and the oligomeric compounds were characterized using various techniques. Optical and electrical properties of the complexes were also investigated. All compounds showed indirect band gaps and they can be accepted as being in the semiconductor class. Organic-inorganic hybrid devices were obtained using n-Si inorganic semiconductor and the complexes. The characteristic parameters of the devices were determined using current-voltage (I-V) and capacitance-voltage measurements in the dark. Photoelectrical properties of the devices were investigated using I-V measurements under a solar simulator with an AM1.5 global filter.

“…Testing of genotoxicity is a mandatory and preliminary step in the safety assessments for the newly synthesized chemicals including pharmaceuticals, food additives, and industrial substances [8][9][10]. The bacterial Ames test, developed by Dr. Bruce Ames in 1975, is a widely used screening test for the possible genotoxic effects of chemical compounds (the ability to induce mutation or cancer) [11].…”

Two new Schiff base ligands (L 1 , L 2 ) have been prepared from the reaction of 2,6-diacetylpyridine and 2-pyridinecarboxyaldehyde with 4-amino-2,3-dimethyl-1-phenyl-3-pyrozolin-5-on, and their Co(II), Cu(II), Ni(II), Mn(II), and Cr(III) metal complexes have also been prepared. The complexes are formed by coordination of N and O atoms of the ligands. Their structures were characterized by physico-chemical and spectroscopic methods. The analytical data shows that the metal to ligand ratio in the Schiff base complexes is 1:2. The Schiff base ligands and all complexes were evaluated for their in vitro antibacterial and antifungal activities by the disc diffusion method. In addition, the genotoxic properties of the ligands were studied.
