The dinuclear title complex, [Co2(C15H8O7)2(H2O)6], lies across an inversion center. The unique CoII ion is coordinated in a slightly distorted octahedral coordination geometry by two O atoms from a chelating 4-(carboxyphenoxy)phthalate ligand, three water O atoms and a further O atom from a bridging carboxylate group of a symmetry-related 4-(carboxyphenoxy)phthalate ligand. In the crystal, O-H...O hydrogen bonds link the molecules into a three-dimensional network.
