In the title compound, Pb(2)(HPO(3))(NO(3))(2), the two distinct Pb(2+) ions (both with site symmetry m) adopt irregular PbO(10) coordination polyhedra. The structure is completed by two distinct nitrate groups (in which one O atom and the N atom have m site symmetry for both ions) and an HPO(3) (2-) anion (in which one O atom and the P and H atoms have m site symmetry). The connectivity of the PbO(10), NO(3) and HPO(3) units in the crystal structure results in a three-dimensional network.
