In the title compound, [Co 2 （CH 3 COO） 4 （C 18 H 18 N 4 ） 2 ]·2C 2 H 5 OH, the asymmetric unit consists of half each of two independent complex molecules, which are located about centres of inversion, and two molecules of ethanol. Each Co II atom is four-coordinated by two N atoms from two 2,2‘-（butane-1,4-diyl）-1 H -benzimidazole ligands and two O atoms from two acetate ions in a slightly distorted tetrahedral coordination environment. In the crystal packing, the molecules are linked by a complex three-dimensional network of N—H?O, O—H?O and O—H?N hydrogen-bond interactions.
