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...

Sumario: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).
