Abstract
In the title compound, C(8)H(6)Cl(2)O(2), the dihedral angle between the C-C(=O)-OH carboxyl unit and the benzene ring is 70.70 (4)°. In the crystal, mol-ecules are linked into inversion dimers by pairs of O-H⋯O hydrogen bonds. The dimers are linked into chains extending along [001] by weak C-H⋯Cl inter-actions.
摘要
在标题化合物C₈H₆Cl₂O₂中，C-C(=O)-OH羧基单元与苯环之间的二面角为70.70 (4)°。在晶体中，分子通过O-H⋯O氢键对连接成反演二聚体。这些二聚体通过弱的C-H⋯Cl相互作用连接成沿[001]方向延伸的链。
