Approach to Synthesis, Characterization, Antimicrobial Activities and Catalytic Activity of Some Transition Metal Complexes Containing Biologically Active Asymmetrical Tetradentate Ligands.
AIR AND MOISTURE STABLE COORDINATION COMPOUNDS OF FIRST TRANSITION METALS SUCH AS CO(II), NI(II) AND CU(II) WITH NEWLY DESIGNED SCHIFF BASE (BSIPH) INCORPORATING 5-BROMOSALICYALDEHYDE WITH ISATIN AND 4-NITRO-O-PHENYLENE DIAMINE HAVE BEEN SYNTHESIZED TO ELUCIDATE THE STRUCTURE OF METAL COMPLEXES. THEY ARE CHARACTERIZED BY ELEMENTAL ANALYSES, INFRARED, 1HNMR, 13CNMR, THERMAL ANALYSIS, UV-VISIBLE, CONDUCTIVITY AND MAGNETIC SUSCEPTIBILITY MEASUREMENTS. THE RESULTS SUGGEST THAT ... Read more

Complexation of Schiff bases incorporating of Salicylaldehyde Derivatives and Amino Acids to Copper(II) as an effective strategy for antimicrobial activity improvement, DNA Interaction and catalytic activity
Five Cu(II) complexes are tridentate Schiff bases amino acids ligands derived from condensation 3–methoxysalicylaldehyde (MS) or 4-diethylaminosalicylaldehyde (DS) with α-amino acids (L-phenylalanine(P), L-histidine (H), DL-tryptophane (T)). All ligands are analyzed by 1HNMR and 13CNMR. The investigated complexes have been prepared and characterized by elemental analysis, infrared spectra, ultraviolet-visible and thermal analysis in dynamic air atmosphere (40ml / min) at a ...

Some New Nano-sized Mononuclear Cu(II) Schiff Base Complexes: Design, Characterization, Molecular Modeling and Catalytic Potentials in Benzyl Alcohol Oxidation
In the present contribution, some novel Cu(II) complexes were synthesized from tri- and tetradentate imine ligands. All the prepared compounds were elucidated by different physicochemical methods. Density Functional Theory calculations were carried out to explain the equilibrium geometry of the bsisnph and npisnph ligands and their Cu(II) complexes. Interaction of the synthesized ligands with Cu(II) affords nano-sized particles via TEM. ... Read more
