title: 3-Meth-oxy-2-[2-({[6-(trifluoro-meth-yl)pyridin-2-yl]-oxy}meth-yl)phen-yl]prop-2-enoic acid.
abstract: The title mol-ecule, C(17)H(14)F(3)NO(4), consists of two nearly planar fragments, viz. the 2-benzyl-oxypyridine (r.m.s. deviation 0.016 Å) and (E)-3-meth-oxy-prop2-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 mol-ecules into dimers that are further connected by C-H⋯O and C-H⋯F inter-actions into (001) layers. In addition, π-π stacking inter-actions are observed within a layer between the pyridine and benzene rings [centroid-centroid distance = 3.768 (2) Å]. The F atoms of the trifluoro-methyl group are disordered over two sets of sites in a 0.53 (4):0.47 (4) ratio.
