Abstract A new series of transition metal complexes with (1) Mn(III), (2) Co(II),
(3) Ni(II) and (4) Cu(II) have been synthesized by the reaction of [6,6

(propane-1,3-diylbis(azanylylidene))bis(methanylylidene))bis(5-isopropyl-2-methyl-
phenol)] with suitable metal salts. The synthesized complexes have been charac-
terized by elemental analysis and spectroscopic techniques. The results of single
crystal structures show that the metal is bonded to the ligand through the phenolic
oxygens and imino nitrogens. Synthesized complexes have been evaluated for
antibacterial activity and antioxidant activity, which shows considerable results.

Introduction
During the past few decades, considerable attention has been paid to the chemistry
of metal complexes of Schiff bases containing nitrogen and oxygen as donor atoms,
which have been found to occupy an important role in the development of the
chemistry of chelate systems [1, 2]. Schiff bases have been reported to possess
