The Mean

The molecule of the title compound, C22H14ClNO2S, is built up from an isoxazole ring linked to a benzothiophene ring system with additional phenyl and 4-chlorophenyl substituents. The benzothiophene system is virtually planar with the largest deviation from the mean plane being 0.041 (2) Å, while the isoxazole ring adopts an envelope conformation. The plane of the benzothiophene ring system is almost perpendicular to those of the phenyl and the 4-chlorophenyl rings, with dihedral angles of 64.76 (10) and 82.81 (10)°, respectively, between them. The phenyl ring is inclined by 85.76 (12)° to the plane of the 4-chlorophenyl ring, which in turn lies close to the plane of the isoxazole ring. In the crystal, molecules are linked by weak C—H...O hydrogen bonds and offset π–π interactions between the aromatic rings of adjacent benzothiophene ring systems. These combine to form a three-dimensional network structure.

Fused Ring System

The asymmetric unit of the title compound, C18H13N3S, is build up from two independent molecules slightly inclined to each other. In each molecule, the imidazo[1,2-a]pyridine ring system is almost planar, with the largest deviation from the mean plane being 0.022 (1) Å in the first molecule and 0.018 (1) Å in the second molecule. The fused-ring system belonging to the first molecule makes dihedral angles of 24.06 (7) and 40.52 (8)° with the thiophenyl and phenyl rings, respectively. The corresponding values observed in the second molecule are nearly the same, namely 25.20 (7) and 38.99 (7)°, respectively. The dihedral angle between the thiophenyl and phenyl rings is 63.47 (9)° in the first molecule and 47.49 (9)° in the second. The cohesion of the crystal structure is ensured by two C—H...N hydrogen bonds between molecules and by three C—H...π interactions, forming a three-dimensional network.

Ring Motif

The title compound, C22H18N4OS, crystallized with four independent molecules (A,B,CandD) in the asymmetric unit. All four molecules have aZconformation about the C=N bond with the benzyl ring being inclined to the indoline ring mean planes by 73.4 (2), 77.9 (2), 73.2 (2) and 77.2 (2)° in moleculesA,B,CandD, respectively. In moleculesAandB, the phenyl ring is inclined to the mean plane of the indoline ring mean plane by 12.0 (2) and 12.2 (2)°, respectively. However, in moleculesCandD, the same dihedral angles are larger,viz.37.3 (2) and 36.4 (2)°, respectively. Consequently, the benzyl and phenyl rings are almost normal to one another in moleculesAandB[dihedral angles = 80.3 (3) and 87.1 (3)°, respectively], while in moleculesCandD, the same dihedral angles are only 48.8 (2) and 43.8 (3)°, respectively. There is an intramolecular N—H...O hydrogen bond in each molecule with anS(6) ring motif. There are also short intramolecular N—H...N and C—H...S contacts in each molecule. In the crystal, molecules are linkedviaC—H...S hydrogen bonds and C—H...π interactions, forming a three-dimensional structure. The crystal was refined as a non-merohedral twin with a final BASF value of 0.110 (1).
