Abstract : In the title compound, 2C24H21N3S· C6H6, the two independent Schiff base molecules (A and B) in the asymmetric unit differ in the orientation of the tetrahydro-benzothio- phene ring system with respect to the carbazole ring system by 180° rotation about the C - C bond in the C - C=N - C linkage. The two molecules also differ in the orientation of the ethyl groups [C - N - C - C torsion angle of 90.7 (3)° in molecule A, and -79.4 (3)° in molecule B]. In molecule B, two methylene C atoms of the cyclo-hexene ring are disordered over two sites with occupancies of 0.58 (1) and 0.42 (1). The cyclo-hexene rings in both molecules adopt half-chair conformations. The dihedral angle between the thio-phene ring and the carbazole ring system is 8.07 (9)° in molecule A [3.10 (9)° in molecule B]. In the crystal structure, the independent molecules are linked into dimers by intermolecular C - H⋯N hydrogen bonds. In addition, C - H⋯π interactions are observed. © 2010.
