|Abstract:||Mercury(ll) complexes of benzimidazole and its derivatives, (viz., benzimidazole (Benz.) (I); lH-2(naphthyl ⍺-azo) benzimidazole (⍺-NaBenz.) (II); and 1 H-2-(arylazo)benzimidazole (III)) of the type HaaBZR, where R=H (a), CH3 (b), -NO₂ (c) and-OH (d) have been synthesized and characterized by elemental analysis, infrared. mass and ¹H NMR spectra. The stoichiometric ratios for the Hg(II) complexes have been identified as (1:1), (1:2) or (2: 1) with the contribution of coordinated water and chloride in complex formation. The probable structures for the mercury(II) complexes are also proposed. The results from mass spectral studies are in agreement with the TGA of the fragmentation and mass losses.|
