Abstract: The centrosymmetric title copper(II) complex, [Cu(C₇H₄NO₄)₂(H₂O)₂], was synthesized via the hydrothermal method at a mild temperature (353 K). The Cu^II ion has a distorted octahedral coordination environment, with two N and two O atoms from the pyridine-2,3-dicarboxylate ligands in a common plane and with two water molecules in axial positions. Hydrogen bonds play an important role in the formation of the three-dimensional structure.
