Nickel complexes of Schiff bases derived from mono/diketone with anthranilic acid: Synthesis, characterization and microbial evaluation

The nickel(II) complexes of the dibasic tridentate Schiff bases viz. Sal-AnthraH(2), HNP-AnthraH(2), HAP-AnthraH(2), HPP-AnthraH(2), Acac-AnthraH(2), Etac-AnthraH(2), and Bzac-AnthraH(2), have been synthesized and characterized by IR, H-1 NMR, mass and electronic spectra, and magnetic and conductance studies. On the basis of analytical data, four-coordinate geometry was proposed for the prepared nickel(II) complexes. The complexes have been found to possess 1:1 stoichiometry. The bio-efficacy of the prepared complexes has been examined against the growth of bacteria and fungi in vitro to evaluate their antimicrobial potential. (C) 2015 The Authors.
