The title polymeric coordination compound, {[Co2(C10H2O8)(H2O)8]·8H2O}n, was obtained by slow diffusion of a dilute aqueous solution of CoCl2 and the sodium salt of benzene-1,2,4,5-tetracarboxylic acid (H4btec) through an agar-agar gel bridge in a U-shaped tube. The two independent Co2+ ions are each situated on an inversion centre and are coordinated in a slightly distorted octa­hedral geometry by four water O atoms and two carboxyl­ate O atoms from two btec4- ligands (-1> symmetry), forming a layer parallel to (11-1). This layer can be described as a mol­ecular two-dimensional square grid with the benzene rings at the nodes and the CoII atoms connecting the nodes. O-H...O hydrogen-bonding interactions involving the coordinating water molecules, the carboxylate O atoms and lattice water molecules lead to the formation of a three-dimensional network.
