The chalcone derivative (E)-1-(4-fluoro­phen­yl)-3-(4-hy­droxy-3-meth­oxy­phen­yl)prop-2-en-1-one monohydrate

The title compound, C(16)H(13)FO(3)·H(2)O, 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, mol­ecules are linked via O—H⋯O hydrogen bonds involving the water mol­ecules, 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 inter­actions [centroid–centroid distance = 3.641 (1) Å] involving inversion-related 4-fluoro­phenyl and 4-hy­droxy-3-meth­oxy­phenyl rings.
