N-[11-(4-Chloro­phen­yl)-11,12-dihydro­benzo[c]phenanthridin-6-yl]benzamide

There are two independent mol­ecules in the asymmetric unit of the title compound, C30H21ClN2O, which differ slightly in the orientation of the unsubstituted phenyl ring. Inter­molecular C—H⋯π inter­actions stabilize the crystal structure. The crystal studied was found to be a racemic twin. The dihedral angles between the substituted phenyl ring and the benzo[c]phenanthridine system are 87.13 (5) and 79.25 (5)° in the two molecules
