1-(Phenyl-sulfon-yl)naphthalene.

In the title compound, C(16)H(12)O(2)S, the phenyl ring is nearly perpendicular to the naphthalene system [dihedral angle = 80.3 (1)°]. The packing is consolidated by a weak C-H⋯π inter-action involving neighbouring naphthalene and benzene rings. In addition, there exist two different offset π-π stacking inter-actions between benzene rings and between naphthalene systems of symmetry-related mol-ecules [centroid-centroid distances = 3.876 (9) and 3.566 (4) Å, and slippage = 1.412 and 0.554 Å, respectively.
