Butane-1,4-diammonium bis(pyridine-2-carboxylate) monohydrate

N.-H. Kim and K. Ha

Abstract: The asymmetric unit of the title compound, C₄H₁₄N₂²⁺·2C₆H₄NO₂^-·H₂O, consists of half of a doubly protonated tetramethylenediammonium dication, a pyridine-2-carboxylate anion and half of a solvent water molecule; the dication is located on a centre of inversion and a twofold rotation axis passes through the O atom of the water molecule. The carboxylate group of the anion appears to be delocalized on the basis of the C-O bond lengths. In the crystal structure, the components are linked by intermolecular N-HO, N-HN and O-HO hydrogen bonds.
