The crystal structure of the title compound, C(4)H(15)N(3) (2+)·C(7)H(3)NO(4) (2-), consists of diethyl-enetriaminium (2,2'-azanediyl-diethanaminium) cations and pyridine-2,5-dicarboxyl-ate anions, which are linked by N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds. C-H⋯π inter-actions are also observed. In the anion, the carboxyl-ate groups are oriented at dihedral angles of 11.04 (15) and 6.31 (14)° with respect to the pyridine ring.
