Synthesis and Characterization of Nickel(II) Complexes of 2-(2´ -Aminophenyl) Benzimidazole

Abstract

Nickel(II) halides reacts with 2-(2´-aminophenyl) benzimidazole

to give complex of the formula NiX₂L₂ where X = Cl^–, Br^–, L =

2-(2´-aminophenyl) benzimidazole. (APBI). These complexes react

with other ligands like glycine, oxalic acid, carboxylic acid and

phenol to form ternary metal complexes. These complexes have

been characterised on the basis of their elemental analysis, conductance

measurement, IR, NMR and electronic Spectra. The fungicidal

action of these metal complexes has been studied against Alternaria

alternata and Spergillus niger by spore germination method compared

with dithane M-45, a commercial fungicide.
