Abstract: In the centrosymmetric dinuclear complex, [Cu₂(C₈H₄O₅)₂(C₁₀H₈N₂)₂(H₂O)₂], the Cu^II 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-HO hydrogen bonds.
