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

The asymmetric unit of the title compound, C(29)H(22)F(2)N(4)O, 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 ac plane. This structure is further consolidated into a three-dimensional architecture by C-H⋯F hydrogen bonding.
