(1RS,6SR)-Ethyl 4-(2,4-dichloro­phen­yl)-6-(4-fluoro­phen­yl)-2-oxocyclo­hex-3-ene-1-carboxyl­ate

There are two symmetry-independent mol­ecules in the asymmetric unit of the title compound, C(21)H(17)Cl(2)FO(3). 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)°. In the crystal, relatively short inter­molecular C—H⋯O inter­actions join mol­ecules into homomolecular (i.e. ⋯AAA⋯ and ⋯BBB⋯) chains along the b axis. These chains are inter­connected by further heteromolecular C—H⋯O inter­actions.
