-acetato--aqua-bis[acetatobis(1H-benzimidazole)cobalt(II)]Abstract: In the title compound, [Co2(C2H3O2)4(C7H6N2)4(H2O)], the half-molecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full molecule. The CoII ions are approximately octahedrally coordinated with a cis-N2O4 coordination sphere. The compound features intramolecular O-H
O hydrogen bonds between the non-bridging acetate groups and the bridging water molecule, and intermolecular N-HO hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the molecular packing in the crystal structure.
