title: Topological analysis of the three-dimensional coordination polymer poly[(μ4-azido)[μ4-5-(pyridin-4-yl)tetrazolido]disilver(I)].
abstract: The title compound, [Ag2(C6H4N4)(N3)]n, was obtained under hydrothermal conditions at 433 K. The asymmetric unit of the orthorhombic space group (Pna21) consists of two Ag(+) cations, an anionic 5-(pyridin-4-yl)tetrazolide (4-ptz(-)) ligand and an anionic azide ligand. Both Ag(+) centres are coordinated by four N atoms, forming a distorted tetrahedral coordination environment. When all the component ions are viewed as 4-connected nodes, the whole three-dimensional network can be regarded topologically as a new kind of 4,4,4,4-connected net with the Schläfli symbol (4.8(5))(4(2).8(4))(4(3).8(3))2.
