10-(4-Fluoro-phen-yl)-4-[(4-fluoro-phen-yl)amino]-5-phenyl-5,8,9,10-tetra-hydro-pyrimido[4,5-]quin-olin-6(7)-one.

The asymmetric unit of the title compound, CHFNO, consists of one mol-ecule in which the pyrimidinyl and anilinyl units exhibit near coplanarity, subtending a dihedral angle of 10.22 (7)°. In contrast, the di-hydro-pyridine and phenyl rings are nearly perpendicular, making angles of 88.66 (7) and 89.14 (7)°. The crystal packing features alternating C-H⋯π and C-F⋯π inter-actions that generate a corrugated two-dimensional supra-molecular network in the crystallographic plane. This structure is further consolidated into a three-dimensional architecture by C-H⋯F hydrogen bonding.
