Abstract: In the title compound, [Cu(C₇H₃NO₄)(C₅H₅N)]_n, the Cu^II atom is in a slightly distorted octahedral coordination environment. Each Cu^II atom is bound to two N atoms and one O atom of the pyridinedicarboxylate (PDA) ligand in a tridentate manner, one N atom of the pyridine molecule and two bridging carboxylate O atoms of adjacent PDA ligands, leading to a linear one-dimensional chain running along the c axis. These chains are further assembled via weak C-HO and - interactions into a three-dimensional supramolecular network structure. The centroid-centroid distance between the - interacting pyridine rings is 3.9104 (13) Å. The two N atoms are trans to each other with respect to Cu.
