Abstract: The title compound, [ZnCl₂(C₁₂H₈N₄S)]_n, was obtained by crystallization of 2,5-di-4-pyridyl-1,3,4-thiadiazole with ZnCl₂ in an MeOH/CHCl₃ solvent system. The structure contains infinite chains of ZnCl₂ units connected by the bifunctional thiadiazole ligands, with Zn^II adopting a distorted tetrahedral coordination geometry. The dihedral angle between the two pyridyl rings in each ligand is 34.3 (1)°, and the dihedral angles between the thiadiazole ring and the two pyridyl rings are 18.3 (2) and 16.1 (2)°. The shortest ZnZn distance within each polymeric chain is 11.862 (3) Å, while the shortest interchain ZnZn distance is 7.057 (3) Å.
