Abstract:
The title compound, C16H13FO3·H2O, has a cis disposition of the carbonyl and olefin bonds about the enone single bond. The arene rings are inclined to one another by 10.05 (6) Å. In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds involving the water mol-ecules, forming loops which are, in turn, linked via O-H.·O and C-H⋯F hydrogen bonds, forming sheets lying parallel to (103). These networks are linked via π-π inter-actions [centroid-centroid distance = 3.641 (1) Å] involving inversion-related 4-fluoro-phenyl and 4-hy-droxy-3-meth-oxy-phenyl rings.
