Biological Advances in Mixed Ligand Complexes with Schiff Base

Al-Nahrain Journal of Science
This research focuses on the multifunctional character of Schiff bases and therefore has a paramount role. Schiff bases are the structural isomers of ketones and imines. They may include secondary aldimines or ketoimines depending on the second carbonyl compound.
