title: 5-Benzoyl-4-(4-fluoro-phen-yl)-3,4-dihydro-pyrimidin-2(1H)-one.
abstract: In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl 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-fluoro-phenyl and benzoyl-phenyl rings, respectively. The dihedral angle between the 4-fluoro-phenyl group and the benzene ring is 71.78 (6)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into inversion dimers that are further connected by another N-H⋯O inter-action into a two-dimensional supra-molecular structure parallel to (101).
