Three novel Ni(II), VO(II) and Cr(III) mononuclear complexes: Synthesis, structural characterization, DNA interaction, antimicrobial evaluation and anticancer activity
Three novel Cr(III),VO(II) and Ni(II) imine complexes derived from the condensation of 2‐aminophenol (AP) with 2‐hydroxynaphthaldehyde (HN) were synthesized. The prepared HNAP imine ligand and its complexes were investigated via various physicochemical tools. The results suggest that the parent ligand behaves as a dibasic tridentate ONO ligand, when coordinated to Cr(III) in octahedral and to Ni(II) in tetrahedral geometry. In ... إقراء المزيد

Recent advances in synthesis, characterization and biological activity of nano sized Schiff base amino acid M (II) complexes
Azomethine amino ligands derived from the condensation of 3-methoxysalicylaldehyde (MS) or 4-diethylaminosalicylaldehyde (DS) with α-amino acids (L-phenylalanine (P) and DL-tryptophan (T)) were synthesized. All ligands were analyzed by IR, 1H NMR, 13C NMR and their melting points. Interaction of the obtained azomethine amino ligands with metal salts produced novel nano sized Fe (II) and Cu (II) complexes. The isolated complexes ... إقراء المزيد

Nano structure Iron (II) and Copper (II) Schiff base complexes of a NNO-tridentate ligand as new antibiotic agents: spectral, thermal behaviors and DNA binding ability
Complexes of Fe (II) and Cu (II) with a tridentate Schiff base, 2-((z)-(pyridine-2-ylimino) methyl) naphthalene1-ol derived from 2-hydroxy-1-napthaldehyde and 2-aminopyridine were synthesized. Both the ligand and its complexes were characterized on the basis of microanalysis, melting point, 1H and 13CNMR, molar conductivity, thermal analysis, IR and UV/Vis spectral studies. From analytical data, the stoichiometry of the complexes was found to ... إقراء المزيد

Desighn, Characterization and Biological activity of new mixed ligand transition metal complexes of glutamine, glutaric and glutamic acid with nitrogen based ligands.
A new series of Cu(II), Co(II), Ni(II) and Fe(II) ternary complexes of glutamine, glutaric and glutamic acid with imidazole derivatives have been synthesized. The nature of bonding and the stereochemistry of the complexes have been deduced from elemental analyses, infrared, electronic spectra, conductivity measurements and thermogravimetric analysis. The structure of [Co(glu)(IMI)2] and [Fe(glu)(IMI)2(H2O)2] complexes was validated using quantum mechanics calculations ... إقراء المزيد
