Abstract

In the crystal structure of the title compound, C(21)H(18)ClFO(3)·0.5C(7)H(8), the toluene solvent mol-ecules occupy special positions on centres of symmetry, and consequently are disordered across this site. The cyclo-hexene ring has a slightly distorted sofa conformation; the two benzene rings are inclined by 72.90 (7)° and their planes make dihedral angles of 30.09 (10) (chloro-phen-yl) and 88.13 (6)° (fluoro-phen-yl) with the approximately planar part of the cyclo-hexenone ring [maximum deviation from plane through five atoms is 0.030 (2) Å, the sixth atom is 0.672 (3)Å out of this plane]. Weak inter-molecular C-H⋯O and C-H⋯X (X = F, Cl) inter-actions join mol-ecules into a three-dimensional structure. Also, a relatively short and directional C-Cl⋯F-C contact is observed [Cl⋯F = 3.119 (2) Å, C-Cl⋯F = 157.5 (2)° and C-F⋯Cl 108.3 (2)°]. The solvent mol-ecules fill the voids in the crystal structure and are kept there by relatively short and directional C-H⋯π inter-actions.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
