Butane-1,4-diammonium bis(pyridine-2-carboxylate) monohydrate
نویسندگان
چکیده
The asymmetric unit of the title compound, C(4)H(14)N(2) (2+)·2C(6)H(4)NO(2) (-)·H(2)O, consists of half of a doubly protonated tetra-methyl-enediammonium dication, a pyridine-2-carboxyl-ate anion and half of a solvent water mol-ecule; the dication is located on a centre of inversion and a twofold rotation axis passes through the O atom of the water mol-ecule. The carboxyl-ate 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 inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds.
