Abstract: In the molecule of the title compound, [ZnCl₂(C₉H₉N₃S)₂], the Zn^II atom is four-coordinated by two N atoms from two 5-m-tolyl-1,3,4-thiadiazol-2-ylamine ligands and two Cl anions in a distorted tetrahedral geometry. Intramolecular N-HN, N-HCl and C-HS hydrogen bonds result in the formation of one planar and one non-planar five-membered, one non-planar six-membered and one non-planar seven-membered ring. The six- and seven-membered rings have twist conformations, while the non-planar five-membered ring adopts an envelope conformation with the S atom displaced by 0.541 (3) Å from the plane of the other ring atoms. The planar five-membered ring is oriented at dihedral angles of 1.74 (3) and 1.08 (3)°, respectively, with respect to the adjacent aromatic and thiadiazole rings. In the crystal structure, intermolecular N-HCl hydrogen bonds link the molecules into a three-dimensional network.
