6-(3,4-Difluorophenyl)-7,8,13,14-tetrahydrodibenzo[c,k]phenanthridine

Abstract

In the title compound, C27H19F2N, the five-fused-ring system is highly puckered and the dihedral angle between the central pyridine ring and pendant difluorobenzene ring is 45.12 (12)°. In the crystal, inversion dimers linked by pairwise weak C—H...N hydrogen bonds generate R22(12) loops and the dimers are further linked by weak C—H...F interactions to form [\overline{1}01] chains.
