Abstract
The asymmetric unit of the title compound, C(7)H(5)ClO(3), contains two mol-ecules; both feature an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, both mol-ecules form inversion dimers linked by pairs of O-H⋯O hydrogen bonds with R(2) (2)(8) ring motifs. The dimers are inter-linked by C-H⋯O inter-actions.
摘要
标题化合物C₇H₅ClO₃的不对称单元包含两个分子；两者均具有分子内O—H⋯O氢键，形成一个S(6)环。在晶体中，两个分子通过成对的O—H⋯O氢键形成具有R₂²(8)环模式的反演二聚体。这些二聚体通过C—H⋯O相互作用相互连接。
