There are two geometrically different mol-ecules in the asymmetric unit of the title compound, C(14)H(9)Cl(2)NO(3). The 5-amino-2-hy-droxy-benzoic acid units [r.m.s. deviations of 0.0323 and 0.0414 Å] and 2,6-dichloro-benzaldehyde groups [r.m.s. deviations of 0.0285 and 0.0226 Å] are roughly planar and oriented at dihedral angles of 11.69 (13) and 83.12 (6)° in the two mol-ecules. An intra-molecular O-H⋯O hydrogen bond completes an S(6) ring motif in each mol-ecule. The two mol-ecules form dimers with each other through inter-molecular O-H⋯N and C-H⋯O hydrogen bonds, completing an R(2) (2)(8) ring motif. The dimers are inter-linked via inter-molecular O-H⋯N and C-H⋯O hydrogen bonds, forming polymeric sheets.
标题化合物C(14)H(9)Cl(2)NO(3)的不对称单元中有两种几何结构不同的分子。5-氨基-2-羟基苯甲酸单元[均方根偏差分别为0.0323和0.0414 Å]和2,6-二氯苯甲醛基团[均方根偏差分别为0.0285和0.0226 Å]大致呈平面状，在两个分子中的二面角分别为11.69 (13)°和83.12 (6)°。分子内的O—H⋯O氢键在每个分子中形成一个S(6)环 motif。两个分子通过分子间的O—H⋯N和C—H⋯O氢键相互形成二聚体，形成一个R(2) (2)(8)环 motif。这些二聚体通过分子间的O—H⋯N和C—H⋯O氢键相互连接，形成聚合物片层。
