Abstract: The crystal structure of the title compound, {(C₂H₁₀N₂)[U(HPO₃)(NO₃)O₂]·2H₂O}_n, consists of polymeric uranyl complex anions, ethylenediammonium cations and uncoordinated water molecules. The polymeric uranyl complex anion displays a ladder-like structure, each UO₂ unit being coordinated by three phosphite dianions and one nitrate anion with a pentagonal-bipyramidal geometry. The ethylenediammonium cation is located on an inversion center and is hydrogen bonded with the uranyl complex.
