title: 2-Phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene.
abstract: There are two molecules in the asymmetric unit of the title compound, C(19)H(12)N(4). One is almost planar [dihedral angle between the fused-ring system and the phenyl ring = 2.16 (13)°] and one is somewhat twisted [dihedral angle = 13.30 (14)°]. In the crystal, the molecules are linked by N-H⋯N hydrogen bonds to result in chains.
