7-(3-Nitro-phen-yl)-9,10-dihydro-7H-benzo[h]cyclo-penta-[b]quinolin-8(11H)-one.
In the title compound, C(22)H(16)N(2)O(3), the naphthalene ring, the 1,4-dihydro-pyridine ring and the cyclo-pent-2-enone ring are nearly coplanar, with the dihedral angles between the neighbouring rings being 1.93 (11) and 2.30 (9)°, respectively. The benzene ring group at position 7 and the 1,4-dihydro-pyridine ring form a dihedral angle of 78.75 (4)°. Inter-molecular N-H⋯O hydrogen bonds and C-H⋯π inter-actions stabilize the crystal packing.
