The title compound, C 18 H 9 Cl 2 F 3 N 4 O, is a tricyclic amide with an overall U-shape. NÐHÁ Á ÁN hydrogen bonds generate linear chains which extend along the a axis.
In the title molecule, C~11~H~11~FN~2~OS, conformational disorder is observed in the tetrahydropyrimidine ring and both components adopt half-chair conformations. In the crystal structure, the molecules are linked by C—H...O and N—H...S hydrogen bonds, forming a sheet-like structure parallel to the
In the title compound, C 16 H 11 FO 2 , a synthetic isocoumarin, the benzene ring is not perpendicular to the planar isocoumarin ring sytem, the dihedral angle being 75.32 (3) . Intermolecular C-HÁ Á ÁO hydrogen bonds may be effective in the stabilization of the crystal structure.
