6-[(2-Hy-droxy-eth-yl)amino]-7H-dibenzo[de,h]quinolin-7-one.
The title compound, C(18)H(14)N(2)O(2), is a new oxoisoaporphine derivative synthesized by alkyl-ation of 6-chloro-1-aza-benzanthrone. The oxoisoaporphine fragment deviates significantly from planarity with a dihedral angle of 5.1 (1)° between the heterocycle and the remote benzene ring. The amino and oxo groups are involved in an intra-molecular N-H⋯O hydrogen bond, while the hy-droxy groups form inter-molecular O-H⋯N hydrogen bonds, which link pairs of mol-ecules into inversion dimers. In the dimer, two approximately parallel oxoisoaporphine fragments exhibit π-π inter-actions between the aromatic rings, the shortest centroid-centroid distance being 3.649 (3) Å.
