Abstract
In the title compound, C22H19NO5S, the carbazole skeleton is nearly planar [maximum deviation = 0.043 (1) Å] with the pyrrole ring oriented at dihedral angles of 2.32 (6) and 1.77 (6)° with respect to the adjacent benzene rings. The dihedral angle between the benzene ring of the tosyl group and the carbazole skeleton is 82.25 (5)°. Intramolecular O—H⋯O hydrogen bonding results in the formation of a planar six-membered ring, which is oriented at a dihedral angle of 3.06 (4)° with respect to the adjacent carbazole skeleton. In the crystal structure, weak intermolecular C—H⋯O interactions link the molecules into infinite chains and π–π contacts between the benzene rings and between the pyrrole and benzene rings [centroid–centroid distances = 3.374 (1) and 3.730 (1) Å, respectively] may further stabilize the structure. A weak C—H⋯π interaction is also present.
