Sumario: | In the crystal structure of the title compound, C(21)H(18)ClFO(3)·0.5C(7)H(8), the toluene solvent molecules occupy special positions on centres of symmetry, and consequently are disordered across this site. The cyclohexene 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) (chlorophenyl) and 88.13 (6)° (fluorophenyl) with the approximately planar part of the cyclohexenone 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 intermolecular C—H⋯O and C—H⋯X (X = F, Cl) interactions join molecules 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 molecules fill the voids in the crystal structure and are kept there by relatively short and directional C—H⋯π interactions. |
