(E)-3-[4-(Dimethyl­amino)­phen­yl]-1-(2-methyl-4-phenyl­quinolin-3-yl)prop-2-en-1-one 0.7-hydrate

In the title compound, C(27)H(24)N(2)O·0.7H(2)O, 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].
