Bis(dicyclohexylammonium) 2,6-Pyridinedicarboxylate Dihydrate

In the title compound, 2C₁₂H₂₄N⁺.C₇H₃NO₄²⁻.2H₂O, one of the ammonium cations is linked to the dianion [N...O = 2.717 (3), 2.846 (3) Å] to form an eight-membered ring; this monoanionic entity is linked to an adjacent entity through the second ammonium cation and a disordered water molecule [N...O = 2.871 (3), 2.908 (3); O...O 2.602 (6), 2.778 (6) Å] to form a linear chain. The second water molecule links two chains through the disordered water molecule [O...O = 2.674 (7), 2.825 (9) Å] into a ribbon running parallel to the a axis.
