title: (3-Ethyl-6,7-dimeth-oxy-naphthalen-1-yl)(phen-yl)methanone.
abstract: The asymetric unit of the title mol-ecule, C(21)H(20)O(3), contains two crystallographically independent mol-ecules, A and B, which differ in the orientation of the ethyl group substituted on the naphthalene system; the dihedral angles between the ethyl group and the naphthalene system are 7.4 (3) and 68.1 (3)°, respectively, for mol-ecules A and B. The dihedral angles between the benzoyl and naphthalene groups are 64.7 (7) and 69.4 (8)°, respectively, for mol-ecules A and B. The crystal structure features four aromatic π-π stacking interactions [centroid-centroid distances = 4.181 (1), 3.891 (1), 4.423 (1) and 4.249 (1) Å].
