title: Hydrogen bonding and pi-pi stacking in hexaaquairon(II) bis(4',7-dimethoxyisoflavone-3'-sulfonate) octahydrate.
abstract: In the structure of the title compound, [Fe(H2O)6](C17H13O7S)2.8H2O, 16 hydrogen bonds exist between the centrosymmetric [Fe(H2O)6]2+ cation, the isoflavone-3'-sulfonate anions and the coordinated and solvent water molecules. pi-pi stacking interactions between the isoflavone units, hydrogen bonding and electrostatic interactions result in a three-dimensional supramolecular structure.
