چکیده
In the title compound, C(26)H(22)Cl(2)O(4), the cyclo-hexenone ring adopts an approximate half-chair conformation, with two C atoms displaced by -0.485 (6) and 0.218 (6) Å from the plane of the other four ring atoms. The dihedral angles between its four almost coplanar [maximum deviation = 0.006 (2) Å] atoms and the benzene and naphthalene ring systems are 59.26 (13) and 79.94 (9)°, respectively. The dihedral angle between the aromatic rings systems is 77.14 (7)°. A short intra-molecular C-H⋯Cl contact generates an S(6) ring. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯Cl inter-actions to generate a three-dimensional network.

In the title compound, C(27)H(26)O(4), the dihedral angle between the naphthalene ring system and the benzene ring is 73.10 (5)°. In the crystal, a weak C-H⋯O inter-action occurs. Two C-H groups of the cyclo-hexene ring are disordered over two sets of sites in a 0.796 (5):0.204 (5) ratio, which corresponds to partial overlap of the two enanti-omeric mol-ecules.

There are two symmetry-independent mol-ecules in the asymmetric unit of the title compound, C(21)H(17)Cl(2)FO(3). Both these mol-ecules 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 mol-ecules at [0.245 (1), 0.535 (19...
