1-(Phenyl-sulfon-yl)benzo[1,2:2',3']thieno[5',4'-b]carbazole
Abstract:
In the title compound, C(24)H(15)NO(2)S(2), the ring system composed of the five fused rings is almost planar (r.m.s. deviation for all non-H atoms = 0.056 Å). The dihedral angle between the fused ring system and the phenyl ring is 83.4 (9)°. The crystal packing is stabilized by C-H⋯π and π-π inter-actions between parallel ring systems [centroid-centroid distances = 3.526 (3), 3.877 (3) and 3.712 (3) Å].

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
