During recent decades, the complexation of organic ligands toward several metal ions of sp
and d-block has been applied as a plan to enhance its antioxidant performance. Due to their …

New medicinally active chelates were prepared from Cu (II), VO (II), Ag (I) and Pd (II) ions
with N-(1H-Benzoimidazol-2-yl)-guanidine, BIG ligand. The ligand performed as bi-dentate …

The main purpose of the current work is the design and synthesis of new Co (II), Ni (II), and
Cu (II) mixed‐ligand complexes derived from simple and easily synthesized azo‐ligand,[2 …

A new Schiff-base ligand, 4-[(4-oxo-4, 5-dihydro-1, 3-thiazol-2-yl) hydrazono] methylphenyl
4-methylbenzenesulfonate (L), and its Fe (III), Co (II), Ni (II), Cu (II) and Zn (II) complexes …

Abstract Four Co (II),(C1); Ni (II),(C2); Cu (II),(C3) and Zn (II),(C4) chelates have been
synthesized with 1-(4-((2-amino-5‑methoxy) diazenyl) phenyl) ethanone ligand (L). The …

This work synthesized three new CrAz2, MnAz2, and FeAz2 complexes and investigated
them using IR, mass, UV spectroscopy, elemental analysis, conductivity and magnetic tests …

Simple Summary The coronavirus was declared a worldwide pandemic for the first time in
December 2019. Although vaccination reduces the risk of severe illness and death, no …

A new heterocyclic azo dye ligand (L) was synthesized by the combination of 4-amino
antipyrine with 4-aminophenol. The new Cr (III), Mn (II), Fe (III), Co (II), Ni (II), Cu (II), Zn (II) …

In this work, we synthesized and studied novel VO (II), Mn (II), Fe (III), Zn (II), and Ag (I)− 4-((2-
hydroxy-1-naphthyl) azo) benzenesulfonamide complexes. Characterization techniques …

Herien, three new Fe (III)(FeAZD), Ni (II)(NiAZD), and Cu (II)(CuAZD) complexes were
synthesized and characterized using various physicochemical and spectroscopic …
