In the title benzonitrile compound, C(12)H(11)F(3)N(2)O, an intra-molecular C-H⋯F hydrogen bond generates an S(7) ring motif. The trifluoro-methyl 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, mol-ecules are connected by inter-molecular C-H⋯F and C-H⋯O inter-actions to form R(2) (2)(8) ring motifs. These inter-actions also link the mol-ecules into chains parallel to the [10[Formula: see text]] direction.
在标题苯甲腈化合物C(12)H(11)F(3)N(2)O中，分子内C-H⋯F氢键生成一个S(7)环 motif。三氟甲基在两个取向间无序，精修占有率比为0.549 (16):0.451 (16)。吗啉环呈椅式构象。苯环与吗啉环的平均平面相互间形成58.04 (10)°的二面角。在晶体中，分子通过分子间C-H⋯F和C-H⋯O相互作用连接形成R(2) (2)(8)环motif。这些相互作用还将分子连接成平行于[10[化学式：见原文]]方向的链。
