title: Crystal structure of 15-(2-chloro-phen-yl)-6b-hy-droxy-17-methyl-6b,7,16,17-tetra-hydro-7,14a-methanona-phtho[1',8':1,2,3]pyrrolo-[3',2':8,8a]azuleno[5,6-b]quinolin-14(15H)-one.
abstract: In the title compound, C34H25ClN2O2, the fused pyrrolidine ring adopts an envelope conformation with the N atom as the flap. The two adjacent cyclo-pentane rings also adopt envelope conformations. The mean plane of the pyrrolidine ring makes dihedral angles of 40.53 (10) and 80.23 (10)° with the mean planes of the cyclo-pentane rings. The dihedral angle between the mean planes of the cyclo-pentane rings is 46.71 (9)°. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal, mol-ecules are linked by C-H⋯O, C-H⋯N and C-H⋯π inter-actions, forming a layer parallel to (10-2).
