2-[(E)-4-Methoxybenzylidene]-1,2,3,4-tetrahydronaphthalen-1-one
Two independent molecules (A and B) comprise the asymmetric unit of the title compound, C(18)H(16)O(2). 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)°, and in the orientations of met...

| description | Two independent molecules (A and B) comprise the asymmetric unit of the title compound, C(18)H(16)O(2). 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)°, 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)°]. The cyclohexene ring of each fused ring system has a screw-boat conformation. In the crystal, C—H⋯π interactions assemble molecules into a supramolecular array in the ab plane. |
