Antioxidant and antitumor activities of Cr (III), Mn (II), Fe (III), Cd (II), Zn (II) and Hg (II) complexes containing a carbohydrazone ligand ending by 4-pyridyl ring
A Fetoh, OA El-Gammal, GMA El-Reash - Journal of Molecular Structure, 2018 - Elsevier
Abstract Cr (III), Mn (II), Fe (III), Cd (II), Zn (II) and Hg (II) complexes derived from
carbohydrazone ligand were synthesized and characterized by spectroscopic methods, DFT
calculations and TGA analysis. IR spectra together with DFT optimization revealed that the
ligand uses its two (Cdouble bondN) azomthine in coordination with either Mn (II), Fe (III) or
Zn (II) ions. While, Cd (II) and Hg (II) ions coordinates via the nitrogen atoms of the two
pyridyl groups. On the other hand, the coordination takes place through the two (Cdouble …
