Abstract: In the title benzonitrile compound, C₁₂H₁₁F₃N₂O, an intramolecular C-HF hydrogen bond generates an S(7) ring motif. The trifluoromethyl group is disordered over two orientations with a refined occupancy ratio of 0.549 (16):0.451 (16). The morpholine ring adopts a chair conformation. The benzene ring and mean plane of the morpholine ring make a dihedral angle of 58.04 (10)° with each other. In the crystal, molecules are connected by intermolecular C-HF and C-HO interactions to form R²₂(8) ring motifs. These interactions also link the molecules into chains parallel to the [10] direction.
