Abstract: In the title compound, {[Co₂(C₁₆H₆O₈)(C₁₂H₈N₂)(H₂O)₂]·H₂O}_n, one Co^II ion has a {CoN₂O₄} distorted octahedral environment defined by two N atoms of one 1,10-phenanthroline (phen) ligand, three O atoms of the carboxylate groups of three biphenyl-3,3',4,4'-tetracarboxylate (BPTC) ligands, one of which is bidentate, and one O atom from one coordinated water molecule. The other Co^II atom is surrounded by six O atoms from four different BPTC ligands and one coordinated water molecule. Each BPTC ligand forms eight coordination bonds with seven Co^II atoms, leading to a layer structure along the ac plane. Uncoordinated water molecules occupy the space between the layers, and interact via interlayer O-HO hydrogen bonds along the b axis, generating a three-dimensional supramolecular network.
