Abstract: Ferric sulfate reacts with 1,6-diaminohexane in the presence of acid under hydrothermal conditions to form the title compound, (C6H18N2)[Fe(OH)(SO4)2]·H2O. The six-coordinate ferrate trianion exists as a [mu]2-hydroxodi-[mu]2-sulfate-bridged chain that propagates along the b axis of the monoclinic unit cell. The dication and uncoordinated water molecule connect the polyanionic chain into a three-dimensional network structure. The asymmetric unit contains two Fe ions, each on a center of symmetry.
