4-Amino-3-(4-chloro-phen-yl)-1H-1,2,4-triazole-5(4H)-thione.

ABSTRACT: In the title compound, C(8)H(7)ClN(4)S, the benzene ring is statistically disordered over two conformations rotated about the Cl-C?C-C axis, which subtend dihedral angles of 24.7?(3) and 9.9?(2) ° with respect to the triazole ring. An intra-molecular C-H?N close contact occurs. In the crystal, N-H?N and N-H?S hydrogen bonds link the mol-ecules into (001) sheets: R(2) (2)(8) and R(2) (2)(10) graph-set motifs result. Weak C-H?N hydrogen bonds and aromatic ?-? stacking inter-actions [shortest centroid-centroid separation = 3.681?(7)?Å] complete the structure.

In the title compound, C(8)H(7)ClN(4)S, the benzene ring is statistically disordered over two conformations rotated about the Cl-C⋯C-C axis, which subtend dihedral angles of 24.7 (3) and 9.9 (2) ° with respect to the triazole ring. An intra-molecular C-H⋯N close contact occurs. In the crystal, N-H⋯N and N-H⋯S hydrogen bonds link the mol-ecules into (001) sheets: R(2) (2)(8) and R(2) (2)(10) graph-set motifs result.
