(2E)-3-(4-Eth-oxy-phen-yl)-1-(2-methyl-4-phenyl-quinolin-3-yl)prop-2-en-1-one monohydrate

Abstract

The title hydrate, C(27)H(23)NO(2)·H(2)O, 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, mol-ecules related by the 2(1) symmetry operation are linked along the b axis via water mol-ecules that form O-H⋯O(c) and O-H⋯N(q) hydrogen bonds (c = carbonyl and q = quinoline). A C-H⋯O inter-action also occurs.
