catena-Poly[zinc(II)-bis­[μ-5-(2-amino­phenyl)tetra­zolato]-κ(3) N (1),N (5):N (2);κ(3) N (2):N (1),N (5)]

The polymeric title compound, [Zn(C(7)H(6)N(5))(2)](n), was synthesized by the hydro­thermal reaction of Zn(NO(3))(2) with 2-amino­benzonitrile in the presence of NaN(3). The zinc(II) metal centre displays a distorted octa­hedral coordination environment provided by N atoms of two bidentate chelating and two monodentate 5-(2-amino­phen­yl)tetra­zolate ligands. These ligands act as bridges, linking adjacent Zn atoms into polymeric criss-crossed chains parallel to the [110] and [[Image: see text]10] directions. Intra­chain N—H⋯N hydrogen-bonding inter­actions are observed.
