catena-Poly[zinc(II)-bis[μ-5-(2-aminophenyl)tetrazolato]-κ³N¹,N⁵:N²;κ³N²:N¹,N⁵]

Abstract

The polymeric title compound, [Zn(C(7)H(6)N(5))(2)](n), was synthesized by the hydro-thermal reaction of Zn(NO(3))(2) with 2-amino-benzonitrile in the presence of NaN(3). The zinc(II) metal centre displays a distorted octa-hedral coordination environment provided by N atoms of two bidentate chelating and two monodentate 5-(2-amino-phen-yl)tetra-zolate ligands. These ligands act as bridges, linking adjacent Zn atoms into polymeric criss-crossed chains parallel to the [110] and [10] directions. Intra-chain N-H⋯N hydrogen-bonding inter-actions are observed.
