2,3-Dimeth-oxy-5,12-tetra-cenequinone.

ABSTRACT: The mol-ecule of the title compound, C(20)H(14)O(4), is approximately planar [maximum deviation 0.168 (2) Å]. The two meth-oxy groups are slightly twisted relative to the plane of the 5,12-tetra-cenequinone system, with twist angles of 3.3 (3) and 5.6 (2)°. All O atoms are involved in intermolecular C-H⋯O inter-actions and the mol-ecules are arranged into slipped face-to-face stacks along the b axis via π-π inter-actions with an inter-planar distance of 3.407 (2) Å.
