In the title compound, [Li2(C6H3N2O4)2(NO3)]n, the two symmetry-independent LiI ions are each in a trigonal-bipyramidal coordination and are bridged by N,O-bonding ligands, forming molecular ribbons propagating in [010]. Each LiI ion is also coordinated by two O atoms from nitrate ions, connecting the ribbons into a three-dimensional network. Very strong intramolecular O-H...O hydrogen bonds occur between the carboxyl and the carboxylate group.
