These double chains are linked by centrosymmetric pairs of O—H...O hydrogen bonds into layers parallel to (10-1). The asymmetric unit consists of one crystallographically independent NiIIcation, one carboxylate and one DFDI ligand, as well as of one water molecule, all of them located in general positions.
