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

Abstract

The asymmetric unit of the title compound, C4H14N2 2+·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—H⋯O, N—H⋯N and O—H⋯O hydrogen bonds
