In the title molecule, C17H13FN2O2, the 3,4-dihydropyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluorophenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281 (2) Å. This plane forms dihedral angles of 85.98 (6) and 60.63 (6)° with the 4-fluorophenyl and benzoyl-phenyl rings, respectively. The dihedral angle between the 4-fluorophenyl group and the benzene ring is 71.78 (6)°. In the crystal, N—HO hydrogen bonds link molecules into inversion dimers that are further connected by another N—HO interaction into a two-dimensional supramolecular structure parallel to (101).

The asymmetric unit of the title compound, C25H31NO4, contains two independent molecules. In one molecule, the benzene ring and an attached methoxy group were refined as disordered over two sets of sites in a 0.65 (4): 0.35 (4) ratio. In both molecules, the central ring of the acridinedione system adopts a flattened boat conformation. The four essentially planar atoms of this ring [maximum deviations = 0.006 (5) Å in both molecules] forms dihedral angles of 86.8 (2) and 87.6 (2)°, respectively, with the major and minor components in the disordered benzene ring and 87.3 (2)° with the benzene ring in the fully ordered molecule. The two outer rings of the acridinedione system adopt sofa conformations in both molecules. In the crystal, N—HO hydrogen bonds form two independent chains along [100]. C—HO hydrogen bonds link the chains, forming a three-dimensional network.

In the title compound, C32H28F2N2O2, the tetrahydropyridine ring adopts a distorted boat conformation. The two fluorophenyl groups are attached to the tetrahydropyridine ring in a trans orientation. The dihedral angle between the planes of the fluoro-substituted rings is 57.0 (1)°. The amino group and carbonyl O atom are involved in intramolecular hydrogen bonding. In the crystal, weak C—HO, C—HF and C—Hπ interactions link the molecules into columns along [010].
