Y.-L. Fu, Z.-W. Xu, J.-L. Ren and S. W. Ng

Abstract: Ferric sulfate reacts with diethylenetriamine in the presence of acid under hydrothermal conditions to form the title compound, (C₄H₁₆N₃)[Fe(SO₄)₃]·H₂O. The six-coordinate ferrate trianion entity exists as a tri-₂-sulfate-bridged chain that propagates along the c axis of the monoclinic unit cell. The trication and uncoordinated water molecule connect the polyanionic chain into a three-dimensional network structure.
