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

F. Payton-Stewart, S. Ravi Kiran Pingali and J. P. Donahue

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, 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 [pi]-[pi] interactions [centroid-centroid distance = 3.641 (1) Å] involving inversion-related 4-fluorophenyl and 4-hydroxy-3-methoxyphenyl rings.
