2-Amino-4-(2-fluoro-phen-yl)-5,6-dihydro-benzo[h]quinoline-3-carbonitrile.

In the title compound, C(20)H(14)FN(3), the F atom of the fluoro-substituted benzene ring in the 4-position of the 5,6-dihydro-benzo[h]quinoline system is disordered over two positions (0.80 and 0.20 occupancy). The dihedral angle between the pyridine and fluorobenzene rings is 73.2 (2) Å. The crystal structure is established by inter-molecular N-H⋯N hydrogen bonds, forming a three-dimensional network.
