title: Bis[5-(2-amino-3-pyrid-yl)tetra-zolato]copper(II).
abstract: In the centrosymmetric title complex, [Cu(C(6)H(5)N(6))(2)], the Cu(II) ion is coordinated by four N atoms from two symmetry-related bidentate 5-(2-amino-3-pyrid-yl)tetra-zolate ligands in a slightly distorted square-planar environment. There are weak intra-molecular N-H⋯N hydrogen bonds between the two ligands. In the crystal structure, there are significant π-π stacking inter-actions between symmetry-related tetra-zole and pyridine rings, with a centroid-centroid distance of 3.6025 (18)°.
