在标题化合物C17 H13 BrO 4分子中，蒽醌环系轻微弯曲，两个苯环平面间的二面角为169.99（7）°。 侧链（O-C-C-C-Br）具有gauche-gauche构象，如O-C-C-C和C-C-C-Br扭转角分别为−66.9（2）°和−65.8（2）°所示。 此外，分子内存在一个O-H-O氢键，围绕着一个S（6）环基序。氢键供体是分叉的;在晶体中，一对O-H-O氢键连接两个分子，形成具有R22（12）环基序的反转二聚体。
In the molecule of the title compound, C17H13BrO4, the anthraquinone ring system is slightly bent, with a dihedral angle of 169.99 (7)° between the planes of the two benzene rings. The side chain (O—C—C—C—Br) has a gauche–gauche conformation, as indicated by the O—C—C—C and C—C—C—Br torsion angles of −66.9 (2) and −65.8 (2)°, respectively. In addition, there is an intramolecular O—H⋯O hydrogen bond enclosing an S(6) ring motif. The hydrogen-bond donor is bifurcated; in the crystal, a pair of O—H⋯O hydrogen bonds connects two molecules, forming an inversion dimer with an R22(12) ring motif.
