Figure 1
The mol­ecular structures of the ions comprising the title salt, showing the atom-labelling scheme and displacement ellipsoids at the 50% probability level: (a) 2-({[(pyridin-1-ium-2-ylmeth­yl)carbamo­yl]formamido}­meth­yl)pyridin-1-ium, and (b) 3,5-di­carb­oxy­benzoate; unlabelled atoms are related by the symmetry operation −x, 1 − y, 1 − z.
