Abstract: The crystal structure of the title compound, [Co(C3H2O4)(C7H6N2)(H2O)]n, consists of two-dimensional polymeric CoII complex layers. The octahedral coordination around a CoII atom is composed of a chelate malonate, two monodentate malonate anions from the adjacent asymmetric unit, a bezimidazole ligand and a coordinated water molecule. Each malonate dianion links three CoII atoms related by an n-glide plane to form polymeric layers in the (010) plane. - stacking of the benzimidazole ligands occurs between adjacent polymeric layers, the separation between parallel benzimidazole rings being 3.42 (2) Å.
