Abstract: In the title compound, [Cu(C₉H₈NO₄)₂(H₂O)₄]·4H₂O, the Cu atom lies on an inversion centre. It has a distorted octahedral coordination, formed by two O atoms of two monodentate monoanionic 2,6-dimethylpyridinium-3,5-dicarboxylate ligands and four water molecules. The extensive system of hydrogen bonding, which involves pyridinium NH groups and both coordinated and uncoordinated water molecules, links all residues into an infinite three-dimensional network.
