Abstract: The asymmetric unit of the title compound, [Cu(C₇H₃NO₄)(H₂O)₃], comprises a distorted tetragonally elongated octahedral copper(II) centre coordinated equatorially by a tridentate 2,6-pyridinedicarboxylate anion [Cu-N 1.9093  (14), and Cu-O 2.0368  (11) and 2.0397  (11)  Å] and a strongly bound water molecule [Cu-O 1.9047  (12)  Å] and axially by two weakly bound water molecules [Cu-O 2.3631  (12) and 2.4739  (12)  Å]. The extended structure is based on a layered arrangement in which sheets of stacked molecular units are alternately linked by hydrogen-bonding and - stacking interactions.
