title: catena-Poly[[dichloridozinc(II)]-μ-2,5-di-4-pyridyl-1,3,4-thia-diazole-κN:N].
abstract: The title compound, [ZnCl(2)(C(12)H(8)N(4)S)](n), was obtained by crystallization of 2,5-di-4-pyridyl-1,3,4-thia-diazole with ZnCl(2) in an MeOH/CHCl(3) solvent system. The structure contains infinite chains of ZnCl(2) units connected by the bifunctional thia-diazole ligands, with Zn(II) adopting a distorted tetra-hedral coordination geometry. The dihedral angle between the two pyridyl rings in each ligand is 34.3 (1)°, and the dihedral angles between the thia-diazole ring and the two pyridyl rings are 18.3 (2) and 16.1 (2)°. The shortest Zn⋯Zn distance within each polymeric chain is 11.862 (3) Å, while the shortest inter-chain Zn⋯Zn distance is 7.057 (3) Å.
