2-[(E)-4-Meth-oxy-benzyl-idene]-1,2,3,4-tetra-hydro-naphthalen-1-one.
Two independent mol-ecules (A and B) comprise the asymmetric unit of the title compound, C(18)H(16)O(2). Mol-ecule 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)°, and in the orientations of meth-oxy 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)°]. The cyclo-hexene ring of each fused ring system has a screw-boat conformation. In the crystal, C-H⋯π inter-actions assemble mol-ecules into a supra-molecular array in the ab plane.
