title: Dichloridobis(5-m-tolyl-1,3,4-thia-diazol-2-ylamine-κN)zinc(II).
abstract: In the mol-ecule of the title compound, [ZnCl(2)(C(9)H(9)N(3)S)(2)], the Zn(II) atom is four-coordinated by two N atoms from two 5-m-tolyl-1,3,4-thia-diazol-2-ylamine ligands and two Cl anions in a distorted tetra-hedral geometry. Intra-molecular N-H⋯N, N-H⋯Cl and C-H⋯S 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 thia-diazole rings. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional network.
