(2E)-3-(2-Fluoro­phen­yl)-1-(4-fluoro­phen­yl)prop-2-en-1-one

In the title compouund, C₁₅H₁₀F₂O, the mol­ecule exists in an E conformation with respect to the C=C bond [1.3382 (16) Å]. The dihedral angle between the fluoro-substituted benzene rings is 6.80 (6)° and the whole mol­ecule is roughly planar (r.m.s. deviation for the non-H atoms = 0.069 Å). In the crystal, mol­ecules are linked by C—H...F and C—H...O inter­actions into sheets lying parallel to the bc plane.

Ethyl 6-(4-meth­oxy­phen­yl)-2-oxo-4-phenyl­cyclo­hex-3-ene­carboxyl­ate

The asymmetric unit of the title compound, C₂₂H₂₂O₄, consists of two independent mol­ecules (A and B). The cyclo­hexene rings adopt slightly distorted sofa conformations in both mol­ecules. The dihedral angles between the benzene rings are 74.16 (13) and 71.85 (13)° in mol­ecules A and B, respectively. In the crystal, weak C—H...O hydrogen bonds link the mol­ecules into a ribbon-like structure along the b axis. Weak C—H...π inter­actions are also observed.
