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.
