Abstract: In the title hydrate, C19H15N3O3·H2O, the three aromatic groups in the quinoline derivative are close to coplanar: the central oxadiazole fragment makes dihedral angles of 15.7 (2)° with the benzene ring and 5.30 (14)° with the quinoline ring system. In the crystal, the organic molecules are connected with water molecules by pairs of O-HN hydrogen bonds involving the quinoline and oxadiazole N atoms. The molecules form stacks along the a axis, neighboring molecules within each stack being related by inversion and the shortest distance between the centroids of the oxadiazole and pyridine rings being 3.500 (2) Å. Molecules from neighboring stacks are linked by weak C-HO hydrogen bonds, forming a three-dimensional structure.
