Ethyl 4-(2,4-dichlorophenyl)-6-(6-methoxy-2-naphthyl)-2-oxocyclohex-3-ene-1-carboxylate

In the title compound, C26H22Cl2O4, the cyclohexenone ring adopts an approximate half-chair conformation, with two C atoms displaced by -0.485 (6) and 0.218 (6) angstrom from the plane of the other four ring atoms. The dihedral angles between its four almost coplanar [maximum deviation = 0.006 (2) angstrom] atoms and the benzene and naphthalene ring systems are 59.26 (13) and 79.94 (9)degrees, respectively. The dihedral angle between the aromatic rings systems is 77.14 (7)degrees. A short intramolecular C-H center dot center dot center dot Cl contact generates an S(6) ring. In the crystal, molecules are linked by C-H center dot center dot center dot O and C-H center dot center dot center dot Cl interactions to generate a three-dimensional network.
