In the centrosymmetric dinuclear complex, [Cu2(C8H4O5)2(C10H8N2)2(H2O)2], the CuII ion is coordinated by two N atoms from a bipyridine ligand, three O atoms from two 3-carboxy-2-oxidobenzoate dianions and the O atom of the water molecule in a distorted octahedral geometry. The Cu--O(H) coordination [2.931 (3) Å] is very weak. In the crystal structure, the dinuclear units are linked into a two-dimensional network parallel to (010) by O-H...O hydrogen bonds.
