The mol-ecule of the title compound, C(11)H(7)ClO(3), is planar, with a maximum deviation of 0.0383 (10) Å from the naphthoquinone plane. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds. Short intra-molecular Cl⋯O [2.8234 (8) Å] and O⋯O [2.5530 (11) Å], and inter-molecular Cl⋯Cl [3.2777 (3) Å] contacts further stabilize the crystal structure.
标题化合物C(11)H(7)ClO(3)的分子呈平面结构，与萘醌平面的最大偏差为0.0383 (10) Å。分子内O—H⋯O氢键形成一个S(6)环 motif。晶体堆积通过分子间C—H⋯O氢键得以稳定。短的分子内Cl⋯O [2.8234 (8) Å]和O⋯O [2.5530 (11) Å]以及分子间Cl⋯Cl [3.2777 (3) Å]接触进一步稳定了晶体结构。
