title: 1,8-Bis(tos-yloxy)-9,10-anthraquinone.
abstract: In the crystal structure of the title compound, C(28)H(20)O(8)S(2), adjacent anthracene skeletons are parallel or inclined at an angle of 20.6 (1)°. In the mol-ecular structure, the mean plane of the anthracene skeleton makes dihedral angles of 49.6 (1) and 76.8 (1)° with the tosyl rings, and the two terminal benzene rings are oriented at an angle of 74.5 (1)° with respect to each other. The crystal structure is stabilized by inter-molecular C-H⋯O and C-O⋯π inter-actions.
