The title compound, C(28)H(22)O(6)S(2)·2C(6)H(13)N·2H(2)O, was prepared by the reaction of a Wittig reagent and 2-formyl-benzene-sulfonic acid. The main molecule lies about an inversion centre at the midpoint of the C-C bond between the inner benzene rings. The mol-ecular conformation is stabilized by intramolecular hydrogen bonds. The crystal structure is further stabilized by O-H⋯O and N-H⋯O hydrogen-bonding inter-actions.
标题化合物C(28)H(22)O(6)S(2)·2C(6)H(13)N·2H(2)O是通过维蒂希试剂与2-甲酰基苯磺酸反应制备的。主要分子位于内苯环之间C-C键中点的一个倒转中心周围。分子构象通过分子内氢键得以稳定。晶体结构通过O-H⋯O和N-H⋯O氢键相互作用进一步稳定。
