Synthesis, Spectral Studies and Antimicrobial Activity of Schiff Bases Derived from 4,4'-Diaminodibenzyl with Substituted Salicylaldehydes and Metal Complexes with Mn(II),VO(II) and UO2(II)

Abstract

A series of polydentate Schiff bases have been prepared by the condensation of 4-4'- diaminodibenzyl with different aldehydes such as salicylaldehyde and substituted salicylaldehydes. The Schiff bases characterized by elemental analysis and spectral methods. The metal complexes of Mn(II), VO(II) and UO₂(II) have been prepared by the reaction of Schiff bases. The analytical and spectral data support the octahedral structure for Mn(II) and UO₂(II) and square pyramidal for VO(II) complexes. The antimicrobial activities of Schiff bases and their metal complexes have been studied by screening the compounds against micro organisms such as E. coli, S. typhi, B. subtilis and S. aureus.
