Abstract

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