title: 2,2'-[(Biphenyl-4,4'-di-yl)di(ethene-1,2-di-yl)]dibenzene-sulfonic acid-4-methyl-piperidine-water (1/2/2).
abstract: 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.
