title: 6,6'-oxydichroman.
abstract: The title compound, C(18)H(18)O(3), was synthesized from dichroman in concentrated sulfuric acid. The mol-ecule has a twofold axis passing through the central O atom. The dihedral angle between the two symmetry-related benzene rings is 63.6 (3)°. Weak C-H⋯π inter-actions are present in the structure.
