Cyclohexane-1,2-diammonium bis(pyridine-2-carboxylate)

In the dication of the title salt, C6H16N22+·2C6H4NO2−, the two ammonium groups are in the equatorial positions of the chair-shaped cyclohexyl ring. In the crystal, the cations and anions are linked by N—H...O and N—H...N hydrogen bonds, forming a layer network parallel to the ac plane. Weak π–π interactions between adjacent pyridine rings with a centroid–centroid distance of 3.589 (2) Å are also present
