Abstract: The molecule of the title compound, C₂₀H₁₄O₄, is approximately planar [maximum deviation 0.168 (2) Å]. The two methoxy groups are slightly twisted relative to the plane of the 5,12-tetracenequinone system, with twist angles of 3.3 (3) and 5.6 (2)°. All O atoms are involved in intermolecular C-HO interactions and the molecules are arranged into slipped face-to-face stacks along the b axis via - interactions with an interplanar distance of 3.407 (2) Å.
