Abstract

A zig-zag one-dimensional Mn(III) coordination polymer, {[C₆H₄(O)CHN(CH₂)₂NCH(O)C₆H₄]Mn(N₃)}_n (1) has been synthesized reacting a manganese salt with the Schiff base precursor H₂L, obtained condensing salicyldehyde and ethylenediamine. The compound has been characterized by IR, UV–Vis and EPR spectroscopy. Single crystal X-ray diffraction studies have revealed that the Mn atom possesses a distorted octahedral environment and the metals connected by end-to-end azido ligands lead to the formation of 1-D zig-zag molecular chains. Temperature dependent magnetic studies have shown the presence of weak anti-ferromagnetic coupling among the Mn centers. Cyclic voltammetry has evidenced the presence of a reversible redox couple for the Mn³⁺/Mn²⁺ system. Both the ligand and complex 1 exhibit anti-mycobacterial activity and considerable efficacy on Mycobacterium tuberculosis H37Rv ATCC 27294 and M. tuberculosis H37Ra ATCC 25177 strains. The cytotoxicity study on different human cancer cell lines (Caco 2, MCF7 and A549) suggests that complex 1 has potential anticancer properties.
