2,3-Dimeth­oxy-5,12-tetra­cenequinone

The mol­ecule of the title compound, C(20)H(14)O(4), 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...

Sumario:The mol­ecule of the title compound, C(20)H(14)O(4), 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—H⋯O inter­actions and the mol­ecules are arranged into slipped face-to-face stacks along the b axis via π–π inter­actions with an inter­planar distance of 3.407 (2) Å.
