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.
