Unsymmetrical Schiff Base Functionalized as Monobasic Tridentate Ligand on Complexation with Some Transition Metal Ions

Cu(II), Co(II), Ni(II) and Mn(II) complexes of Schiff base derived from 2‐aminophenol and pyrrole‐2‐ carbaldehyde have been prepared. The complexes are formed by coordination of N and O atoms of the ligand. Their structures were characterized by physico‐chemical and spectroscopic methods. Molecular structure of the complexes has been optimized by MM2 calculations and suggests a tetrahedral/ square planar geometry. The bio‐efficacy of the ligand and their complexes has been examined against the growth of bacteria in vitro to evaluate their anti‐microbial potential.
