Abstract
In the title compound, C10H8FN3O·0.5H2O, the dihedral angle between the mean planes of the rings is 99.80 (4)°. The water molecule lies on a twofold axis. Weak intermolecular O—H...N and C—H...O hydrogen bonds link one water molecule with four phenylethanone molecules, while intermolecular C—H...O hydrogen bonds involving the ketone group link phenylethanone molecules into layers parallel to (100).
