Hydrogen bonding and - stacking in methylaminium 4',7-dihydroxyisoflavone-3'-sulfonate dihydrate and hexaaquairon(II) bis(4',7-diethoxyisoflavone-3'-sulfonate) tetrahydrate

Abstract: In methylaminium 4',7-dihydroxyisoflavone-3'-sulfonate dihydrate, CH₆N⁺·C₁₅H₉O₇S^-·2H₂O, 11 hydrogen bonds exist between the methylaminium cations, the isoflavone-3'-sulfonate anions and the solvent water molecules. In hexaaquairon(II) bis(4',7-diethoxyisoflavone-3'-sulfonate) tetrahydrate, [Fe(H₂O)₆](C₁₉H₁₇O₇S)₂·4H₂O, 12 hydrogen bonds exist between the centrosymmetric [Fe(H₂O)₆]²⁺ cation, the isoflavone-3'-sulfonate anions and the solvent water molecules. Additional [pi] - [pi] stacking interactions generate three-dimensional supramolecular structures in both compounds.

Formula: CH₆N⁺·C₁₅H₉O₇S^-·2H₂O and [Fe(H₂O)₆](C₁₉H₁₇O₇S)₂·4H₂O
