title: Bis(4-eth-oxy-phen-yl) sulfoxide.
abstract: In the title compound, C(16)H(18)O(3)S, the dihedral angle between the benzene rings is 82.7 (2)°. The O atom of the sulfoxide group is disordered over two orientations with refined occupancy factors of 0.563 (3):0.437 (3). In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, forming chains along the b axis.
