In the title complex, [Cu(C6H4N5)2], the CuII ion lies on an inversion center and is coordinated by two chelating 5-(pyridin-2-yl)tetrazolide ligands in a slightly distorted square-planar coordination geometry. In the crystal, π–π stacking interactions, with centroid–centroid distances in the range 3.4301 (14)–3.4387 (13) Å, link the complex molecules along [101].
