Abstract
The asymmetric unit of the title compound, C(22)H(22)O(4), consists of two independent mol-ecules (A and B) which differ significantly in the orientations of ethyl carboxyl-ate groups. The phenyl ring in mol-ecule B is disordered over two orientations with occupancies of 0.55 (2) and 0.45 (2). The cyclo-hexenone ring of both mol-ecules adopts an envelope conformation. The dihedral angle between the two aromatic rings is 81.12 (7)° in mol-ecule A and 70.8 (3)° in mol-ecule B [57.5 (4)° in the minor disorder component]. The crystal structure is stabilized by weak intermolecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
