(E)-2-[(Furan-2-yl)methyl­idene]-7-methyl-2,3,4,9-tetra­hydro-1H-carbazol-1-one

In the title mol­ecule, C₁₈H₁₅NO₂, the atoms in the carbazole unit deviate from planarity [maximum deviation from mean plane = 0.1317 (12) Å]. The pyrrole ring makes dihedral angles of 1.01 (8) and 18.56 (10)° with the benzene and furan rings, respectively. The cyclo­hexene ring adopts a half-chair conformation. In the crystal, pairs of N—H...O hydrogen bonds form an R₂²(10) ring. Mol­ecules are further linked by C—H...O and C—H...π inter­actions, forming a three-dimensional network.
