N2  - A number of mixed-ligand cobalt(III) complexes containing either the ligand 2-aminomethylbenzimidazole (ambi) or its N-methyl derivative, namely 2-(N-methylaminomethyl)benzimidazole (mambi), have been prepared in relatively low yield; in particular, the complexes &#91;Co(ambi)(acac)2&#93; Cl, &#91;Co(ambi)(Clacac)2&#93; Cl, K&#91;Co(ambi)(ox)2&#93;,&#91;Co(ambi)2(acac)&#93; (ClO4)2, &#91;Co(mambi)(acac)2&#93; Cl and &#91;Co(mambi)(Clacac)2 &#93;Cl (acac = acetylacetonate, Clacac = 3-chloroacetylacetonate, ox = oxalate). The reduction potentials of these complexes have been measured in order to assess whether molecules of this type could be potential redox-activated hypoxic cell selective anticancer agents. The complex &#91;Co(ambi)(acac)2&#93; Cl.4&#183;1H2O was characterized by single-crystal X-ray crystallography: a 19&#183;425(1), b 17&#183;734(1), c 15&#183;979(1) &#197;, &#946; 117&#183;52(1)&#x02DA;, monoclinic, space group C 2/c (No. 15)
