Preparation and Characterization of Some Cobalt(III) Complexes of 2-Aminomethylbenzimidazole

Abstract

The coordination chemistry of 2-aminomethylbenzimidazole (ambi) has been studied with cobalt(III), and the cationic complexes fac-[Co(ambi),3]3+, asym-[Co(en) (ambi)2]3+ and [Co(en)2(ambi)]3+ have been prepared. The last cation, in the form of the chloride salt [Co(en)2(ambi)] Cl3.H2O, has been structurally characterized: monoclinic, space group P 21/c, a 7.6692(14), b 14.954(2), c 15.941(3) Ǻ, β 92.64(2)°, Z 4.
