Abstract: In the title compound, [Cu(C₆H₅N₅)₂]_n, the Cu^II atom is coordinated by five N atoms from three distinct pyridyltetrazolate anions in a highly distorted square-pyramidal arrangement. The ligands link adjacent Cu^II atoms to form one-dimensional polymeric chains with a CuCu separation of 6.224 (2) Å. The chains are further linked by - stacking interactions [centroid-centroid = 3.684 (2) Å and vertical distance = 3.281 (2) Å], forming a three-dimensional supramolecular framework.
