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

Abstract

In the title mol­ecule, C ₁₈H ₁₅NO ₂, 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 R ₂ ²(10) ring. Mol­ecules are further linked by C—H⋯O and C—H⋯π inter­actions, forming a three-dimensional network.
