title: 6,7-Dimeth-oxy-1,4-anthraquinone.
abstract: The mol-ecule of the title compound, C(16)H(12)O(4), is almost planar; the two meth-oxy groups are slightly out of the plane of the anthraquinone ring system, with C-C-O-C torsion angles of -6.25 (19) and -10.22 (19)°. In the crystal structure, the mol-ecules adopt a herringbone arrangement and form face-to-face slipped anti-parallel π-π stacking inter-actions along the b axis, with an inter-planar distance of 3.278 (2) Å.
