Abstract

There are two symmetry-independent molecules in the asymmetric unit of the title compound, C21H17Cl2FO3. Both these molecules are very similar: the normal probability plots for bond lengths, angles and even for torsion angles show that the differences are of a statistical nature. A pseudocentre of symmetry is located between the symmetry-independent molecules at 0.245 (1), 0.535 (19), 0.909 (1)]. The cyclohexene rings have slightly distorted sofa conformations in both molecules and the two benzene rings are inclined by dihedral angles of 61.33 (14) and 62.85 (14)degrees. In the crystal, relatively short intermolecular C-H center dot center dot center dot O interactions join molecules into homomolecular (i.e. center dot center dot center dot AAA center dot center dot center dot and center dot center dot center dot BBB center dot center dot center dot) chains along the b axis. These chains are interconnected by further heteromolecular C-H center dot center dot center dot O interactions.
