title: Ethyl 4-(2,4-dichloro-phen-yl)-6-(6-meth-oxy-2-naphth-yl)-2-oxocyclo-hex-3-ene-1-carboxyl-ate.
abstract: 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.
