Abstract: In the title compound, (C₂H₈N)₂[Cu(C₇H₃NO₄)₂], the Cu^II atom lies on an inversion centre and is coordinated in a slightly deformed square-planar geometry by two N and two O atoms from pyridine-2,5-dicarboxylate ligands. The complex anions are linked via weak coordination of an O atom of the 2-carboxylate group to the Cu atom of a neighbouring complex, forming chains along the a axis. There are N-HO hydrogen bonds between dimethylammonium cations and the 5-carboxylate group of the ligand.
