In the title compound, C27H24N2O·0.7H2O, the quinoline ring system is approximately planar, with a maximum deviation of 0.011 (1) Å, and forms dihedral angles of 74.70 (4) and 80.14 (4)° with the phenyl and benzene rings, respectively. In the crystal, the molecules are linked to the water molecules via intermolecular O—H⋯N hydrogen bonds and further stabilized by C—H⋯π interactions involving the centroid of the benzene ring of the quinoline group. This benzene ring is observed to form a π–π interaction with an adjacent pyridine ring [centroid–centroid distance = 3.7120 (6) Å].
