Poly[di-₃-azido-₂-4,4'-bipyridine-dicopper(I)]

F.-C. Liu and J. Ouyang

Abstract: In the crystal structure of the title compound, [Cu₂(N₃)₂(C₁₀H₈N₂)]_n, each Cu^I atom is coordinated by two symmetry-related azide anions and 4,4'-bipyridine (bipy) ligands in a strongly distorted tetrahedral geometry. The Cu atom and the azide anion occupy general positions while the bipy molecule is located on a centre of inversion. Each two symmetry-related copper(I) cations and two symmetry-related azide anions form dimers, which are additionally connected by the anions into layers. These layers are linked by the 4,4'-bipyridine ligands into a three-dimensional coordination network.
