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 π–π stacking interactions generate three‐dimensional supramolecular structures in both compounds. |
