Synthesis of some amino acid Schiff base complexes of vanadium(IV) was done using microwave mode of synthesis and aqueous/semiaqueous medium as solvent. Complexes were characterized by using common analytical and spectroscopic tools such as IR, H-1 NMR, EI Mass, ESR, and magnetic susceptibility measurements. Single-crystal X-ray analysis of one of the complexes was carried out. Antioxidant activity of the complexes was studied using the DPPH scavenging method. The present work attempts to establish a possible structure and antioxidant activity correlation of the synthesized complexes. Some of the complexes show comparable activity to that of the standard reference (i.e., ascorbic acid).
