The asymmetric unit of the title compound, [Li3(C6H5N2O2)2(NO3)(H2O)2]n contains three LiI ions, two ligand anions, two water mol­ecules and a nitrate anion. Related by a centre of inversion, they form a centrosymmetric mol­ecular cluster in which one of the LiI ions shows trigonal–bipyramidal and the other two distorted tetra­hedral coordination. LiI ions are bridged by water O atoms and carboxyl­ate O atoms donated by one of the ligands. The clusters, bridged by two nitrato O atoms, form mol­ecular columns along [010], which are held together by O—H⋯O and O—H⋯N hydrogen bonds and π–π inter­actions [centroid–centroid distances = 3.694 (1) and 3.796 (1) Å]
