(E)-3-[4-(Di-fluoro-meth-oxy)-3-hy-droxy-phen-yl]-1-phenyl-prop-2-en-1-one.

In the title compound, C16H12F2O3, the plane of the phenyl ring makes a dihedral angle of 3.22 (8)° with that of the benzene ring. The mol-ecule has an E conformation about the C=C bond. In the crystal, mol-ecules are linked via pairs of O-H⋯O hydrogen bonds, forming inversion dimers which are further consolidated by a pair of C-H⋯O hydrogen bonds. The dimers are linked via C-H⋯O hydrogen bonds, forming columns along the b-axis direction.

5-(4-Chloro-phen-yl)-1-cyclo-propyl-2-(2-fluoro-phen-yl)-3-phenyl-pentane-1,5-dione.

In the title compound, C(26)H(22)ClFO(2), the cyclo-propane ring makes dihedral angles of 45.7 (2), 49.0 (2) and 65.2 (2)° with the fluoro-substituted phenyl ring, the benzene ring and the chloro-substituted phenyl ring, respectively. The F and Cl atoms deviate by 0.0307 (11) and 0.0652 (6) Å, respectively, from the planes of the phenyl rings to which they are attached. In the crystal, mol-ecules are linked by C-H⋯F hydrogen bonds, forming chains along the b axis.
