Abstract: The title molecule, C17H14F3NO4, consists of two nearly planar fragments, viz. the 2-benzyloxypyridine (r.m.s. deviation 0.016 Å) and (E)-3-methoxyprop2-enoic (r.m.s. deviation 0.004 Å) units, which form a dihedral angle of 84.19 (7)°. In the crystal, pairs of O-H...O hydrogen bonds link molecules into dimers that are further connected by C-H...O and C-H...F interactions into (001) layers. In addition, [pi]-[pi] stacking interactions are observed within a layer between the pyridine and benzene rings [centroid-centroid distance = 3.768 (2) Å]. The F atoms of the trifluoromethyl group are disordered over two sets of sites in a 0.53 (4):0.47 (4) ratio.
