Abstract
The title compound, C(22)H(26)O(9), crystallizes with two independent mol-ecules in the asymmetric unit in which the dihedral angles between the two benzene rings are 21.4 (2) and 5.1 (2)°. An intra-molecular O-H⋯O hydrogen bond occurs in each mol-ecule. Inter-molecular C-H⋯O hydrogen bonds stabilize the crystal structure.
摘要
标题化合物C(22)H(26)O(9)在不对称单元中以两个独立分子结晶，其中两个苯环之间的二面角分别为21.4 (2)°和5.1 (2)°。每个分子中均存在分子内O-H⋯O氢键。分子间C-H⋯O氢键使晶体结构得以稳定。
