In the title compound, C18H12O6, the anthra-quinone ring system is nearly planar [maximum deviation = 0.161 (3) Å] and both acetate groups are located on the same side of the ring plane. A supra-molecular architecture arises in the crystal owing to π-π stacking between parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.883 (4) Å] and weak inter-molecular C-H⋯O hydrogen bonding.
在标题化合物C₁₈H₁₂O₆中，蒽醌环系近乎平面 [最大偏差 = 0.161 (3) Å]，且两个乙酸酯基团位于环平面的同一侧。由于相邻分子的平行苯环之间的π-π堆积 [质心-质心距离 = 3.883 (4) Å] 和弱分子间C-H⋯O氢键，在晶体中形成了超分子结构。
