In the crystal structure of the title solvated molecular salt, C(3)H(12)N(2) (2+)·C(7)H(3)NO(4) (2-)·C(2)H(6)OS, two amine groups of propane-1,3-diamine (pda) are protonated and two carb-oxy-lic acid groups of pyridine-2,5-dicarb-oxy-lic acid (2,5-pydcH(2)) are deprotonated. The crystal packing features N-H⋯O hydrogen bonds and weak C-H⋯O inter-molecular inter-actions.
