(E)-6-Chloro-2-(furan-2-ylmethylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one
Abstract
In the title compound, C17H12ClNO2, the carbazole unit is nearly planar [maximum deviation = 0.052 (1) Å]. The pyrrole ring makes dihedral angles of 1.92 (8) and 4.71 (11)° with the benzene and furan rings, respectively. Intermolecular N—H...O hydrogen bonds form R22(10) rings in the crystal structure.
