| Summary: | In the title compound, C15H13F3N2O2·H2O, the dihedral angle between the benzene and pyridine rings is 74.97 (1)°. The –CF3 group attached to the benzene ring is syn to the C=O bond in the adjacent side chain. In the crystal, molecules are linked to one another through the water molecules by strong N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds, forming a ladder-type network. The benzamide molecules are also linked to one another through C—H⋯F interactions, forming C(6) chains parallel to the b-axis direction. Aromatic π–π stacking interactions [centroid–centroid separations = 3.7150 (1) and 3.7857 (1) Å] between adjacent pairs of pyridine and benzene rings are also observed, resulting in a three-dimensional architecture are also observed.
