The title hydrate, C27H23NO2·H2O, features an almost planar quinoline residue (r.m.s. deviation = 0.015 Å) with the benzene [dihedral angle = 63.80 (7) °] and chalcone [C—C—C—O torsion angle = −103.38 (18)°] substituents twisted significantly out of its plane. The configuration about the C=C bond [1.340 (2) Å] is E. In the crystal, molecules related by the 21 symmetry operation are linked along the b axis via water molecules that form O—H...Oc and O—H...Nq hydrogen bonds (c = carbonyl and q = quinoline). A C—H...O interaction also occurs.
