|Abstract:||Some novel mixed-ligand cyanonitrosyl hetero complexes of chromium( I) of the type [Cr(NO)(CN)2 (L)2 (H2O)], formed by the interaction of potassium pentacyanonitrosylchromate(I) monohydrate, K3[Cr(NO) (CN)5].H2O with benzimadazole(BZL,1), 2-methylbenzimidazole (MBZL, II), 2,5,6-trimethylbenzimidazole (TMBZL,III), 2-chloromethylbenzimidazole (CHMBZL,IV), 2-hydroxymethylbenzimidazole (HYMBZL,V), 2-cyanomethylbenzimidazole (CYMBZL,VI) and 2-aminomethylbenzimidazole (AMBZL,VII) in aqueous acetic acid medium have been characterized on the basis of elemental analyses, molar conductances, molecular weight determinations, magnetic measurements, TGA, ESR, UV/Vis and IR spectral studies. An octahedral structure has been suggested for these complexes. Chromium(I) has a low-spin electron configuration in all the complexes.|
