4-[(E)-2,6-dichlorobenzylideneamino]-3-{1-[4-(2-methylpropyl)phenyl]ethyl} -1H-1,2,4-triazole-5(4H)-thione

Abstract

In the title Schiff base compound, C21H22Cl2N4S, the triazole ring makes dihedral angles of 2.15 (11) and 87.48 (11)°with the 2,6-dichloro-phenyl and methyl-propyl-phenyl rings, respectively. Weak intra-molecular C - H⋯S and C - H⋯Cl inter-actions generate S(6) and S(5) ring motifs, respectively. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by N - H⋯S hydrogen bonds. These dimers are arranged into sheets parallel to the ab plane and are stacked along the c axis. C - H⋯π inter-actions involving the methyl-propyl-phenyl ring and π-π inter-actions involving the dichloro-phenyl ring [centroid-centroid distance = 3.5865 (3) Å] are also observed.
