Poly[bis-(μ(2)-5-n-butyl-tetra-zolato-κN:N)zinc(II)]

Abstract

In the title complex, [Zn(C(5)H(9)N(4))(2)](n), the Zn(II) center is coordinated by four N atoms of different tetra-zolate ligands with a slightly distorted tetra-hedral geometry [Zn-N distances and N-Zn-N angles are in the ranges 1.991 (2)-2.007 (2) Å and 104.22 (8)-116.13 (8)°, respectively]. Each ligand links two Zn(II) atoms through its 1- and 4-position tetra-zole N atoms, forming a single, fully connected three-dimensional framework with a diamond-like topology. In the crystal structure, the Zn⋯Zn separations across each tetra-zole unit are 6.115 (2) and 6.134 (2) Å and the Zn⋯Zn⋯Zn angles are in the range 107.77 (8)-116.83 (8)°.
