1-Cyclo­propyl-2-(2-fluoro­phen­yl)-5-(4-fluoro­phen­yl)-3-phenyl­pentane-1,5-dione

In the title compound, C₂₆H₂₂F₂O₂, the cyclo­propane ring makes dihedral angles of 47.6 (2), 51.3 (2) and 63.9 (2)° with the 2-fluoro-substituted phenyl ring, the unsubstituted phenyl ring and the 4-fluoro-substituted phenyl ring, respectively. There is a short C—H...F contact in the molecule. In the crystal, weak C—H...F hydrogen bonds lead to chains of mol­ecules extending along the b-axis direction.

5-(4-Chloro­phen­yl)-1-cyclo­propyl-2-(2-fluoro­phen­yl)-3-phenyl­pentane-1,5-dione

In the title compound, C₂₆H₂₂ClFO₂, the cyclo­propane 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, mol­ecules are linked by C—H...F hydrogen bonds, forming chains along the b axis.

(E)-3-[4-(Di­fluoro­meth­oxy)-3-hy­droxy­phen­yl]-1-phenyl­prop-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 mol­ecule has an E conformation about the C=C bond. In the crystal, mol­ecules 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.

3-(4-Chloro­phen­yl)-1-cyclo­propyl-2-(2-fluoro­phen­yl)-5-phenyl­pentane-1,5-dione

In the title compound, C₂₆H₂₂ClFO₂, the cyclo­propane ring is disordered over two orientations, with site-occupancy factors of 0.64 (2) and 0.36 (2). The major occupancy component of the cyclo­propane ring makes dihedral angles of 47.6 (7), 50.4 (7) and 65.4 (7)° with the fluoro-, chloro- and unsubstituted benzene rings, respectively [the corresponding values for the minor occupancy component are 47.6 (12), 51.0 (12) and 60.9 (12)°]. An intra­molecular C—H...O hydrogen bond occurs. The F and Cl atoms deviate by 0.0508 (12) and 0.0592 (7) Å from the planes of their attached benzene rings. In the crystal, C—H...F hydrogen bonds link the mol­ecules into chains along the b-axis direction.

3-[(E)-2-(4-Chloro­phen­yl)ethen­yl]-5,5-di­methyl­cyclo­hex-2-en-1-one

In the title compound, C₁₆H₁₇ClO, the cyclo­hexene ring adopts a half-chair conformation and the best plane through the six ring atoms makes a dihedral angle of 6.69 (7)° with the chlorophenyl ring. In the crystal, pairs of C—H...O hydrogen bonds link the mol­ecules into centrosymmetric R₂²(20) dimers. The dimers are linked into an infinite chains along the b-axis direction by further C—H...O hydrogen bonds.
