2,3,6,7-Tetramethoxy-9,10-anthraquinone
Molecules of the title compound, C(18)H(16)O(6), are almost planar [maximum deviation = 0.096 (4) Å] and reside on crystallographic centres of inversion. They adopt a conformation in which the C(methyl)—O bonds are directed along the molecular short axis [C—C—O—C torsion angles of −175.3 (3) and...

| description | Molecules of the title compound, C(18)H(16)O(6), are almost planar [maximum deviation = 0.096 (4) Å] and reside on crystallographic centres of inversion. They adopt a conformation in which the C(methyl)—O bonds are directed along the molecular short axis [C—C—O—C torsion angles of −175.3 (3) and 178.2 (3)°]. In the crystal, molecules adopt a slipped-parallel arrangement with π–π stacking interactions along the a axis with an interplanar distance of 3.392 (4) Å. Weak C—H⋯O interactions link the molecules into sheets parallel to (10-2). |
