Transition Metal Complexes of 1, 4(2′‐Hydroxyphenyl‐1‐yl) di‐imino azine: Synthesis, Characterization and Antimicrobial Studies

The synthesis and characterization of first row transition metal complexes of the 1, 4(2′‐hydroxyphenyl‐1‐yl) di‐imino azine {1,4(2′HPDA)} are reported. The complexes have been characterized by elemental analysis, molar conductance, magnetic studies, IR, 1H NMR and UV‐visible studies. They have the stoichiometry of the type [M{1,4(2′HPDA)} 2 2H 2 O ] and [M′L2] where M= Mn(II), Fe(III), Co(II), Ni(II) and Cu(II), and M′ = ZrO(II), VO(II), Zn(II), Cd(II), and Hg(II). The antibacterial and antifungal activity of the metal complexes has been investigated. Both ligand and complexes have shown good antibacterial and antifungal activity.
