Abstract
Two independent molecules (A and B) comprise the asymmetric unit of the title compound, C18H16O2. Molecule B is virtually superimposable upon A. Minor differences are noted in the dihedral angles between the terminal benzene rings of 56.03 (10) and 54.62 (10)degrees, and in the orientations of methoxy groups with respect to the benzene rings to which they are attached [C-O-C-C torsion angles = 169.11 (19) and -172.37 (18) degrees]. The cyclohexene ring of each fused ring system has a screw-boat conformation. In the crystal, CH center dot center dot center dot pi interactions assemble molecules into a supramolecular array in the ab plane.
