2-Anilino-4-(1,3-benzothia-zol-2-yl)-5-(4-chloro-benzo-yl)thio-phene-3-carbonitrile.

In the title compound, C(25)H(14)ClN(3)OS(2), the central thio-phene ring [maximum deviation = 0.011†(1)†à ] makes dihedral angles of 55.72†(5), 13.36†(5) and 46.77†(4)° with the adjacent chloro-substituted benzene ring, the benzene ring and the 1,3-benzothia-zole ring system [maximum deviation = 0.012†(1)†à ], respectively. An intra-molecular C-H⋯S(thienyl) hydrogen bond generates an S(6) ring motif in the mol-ecule. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds into inversion dimers and the dimers are further connected by C-H⋯O hydrogen bonds into tapes running along [100]. Aromatic π-π stacking inter-actions are also observed [centroid-to-centroid distances = 3.6116†(6) and 3.7081†(6)†à ].
