Transition metal complexes are widely used therapeutic agents due to their small size,
various coordination numbers, geometries, physiologically relevant redox potentials, as well …

In the present study, a series of mononuclear Ni (II), Cu (II) and Zn (II) complexes with ONNO
donor salen-type Schiff base ligands, derived from different 3, 5-dihalosalicylaldehyde with …

Throughout this research, a unique optical sensor for detecting one of the most dangerous
heavy metal ions, Cu (II), was designed and developed. The (4-mercaptophenyl) …

A new Schiff base ligand named as 2, 2'-((1E, 1'E)-((4, 5-dichloro-1, 2-phenylene) bis
(azanylylidene)) bis (methanylylidene)) bis (4-bromophenol) was prepared via condensation …

Abstract The 1: 1 condensation of o-acetoacetylphenol and 1, 2-diaminopropane under
condition of high dilution gives the mono-condensed Schiff base,(E)-3-(1-aminopropan-2 …

Four mononuclear metal chelated complexes,[Co (L)](1),[Ni (L)](2),[Cu (L)](3) and [Zn (L)](4),
were designed and synthesized from a novel quadridentate salen-type Schiff base ligand (H …

Herein we describe the chemical synthesis of a novel tetradentate Schiff base ligand (H 2 L),
bridged with a pyridine, and its corresponding mononuclear copper complex (Cu (II) L). H 2 …

Two chromone hydrazone ligands HL 1 and HL 2 were synthesized and characterized by
elemental analyses, IR, 1 H NMR & 13 C NMR, electronic absorption and mass spectra. The …

Given the widespread and diverse effects of transition metal ions such as copper and zinc in
multiple biological processes, this research endeavor addresses herein the microwave …

Unsymmetrical tetradentate Schiff base Fe (III) and Cu (II) complexes were prepared by the
coordination of some unsymmetrical tetradentate Schiff base ligands with CuCl2· 2H2O or …
