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

N.-H. Kim and K. Ha

Abstract top

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-H...O, N-H...N and O-H...O hydrogen bonds.

Comment top

The title compound, C4H14N22+.2C6H4NO2-.H2O, consists of a doubly protonated tetramethylenediammonium dication, two pyridine-2-carboxylate anions and a solvent water molecule and the asymmetric unit contains one half of the formula unit (Fig. 1); a centre of inversion is located at the mid-point of the dication and the water molecule is disposed about a twofold rotation axis through O atom with the special position at (0, y, 1/4) (Wyckoff letter e). The carboxylate groups of the anions appear to be delocalized on the basis of the C—O bond lengths [C—O: 1.235 (3) and 1.251 (3) Å]. The torsion angles within the dication reveal that all N and C atoms of the dication display the anti conformation. In the crystal structure, the components are linked by intermolecular N—H···O, N—H···N and O—H···O hydrogen bonds (Table 1 and Fig. 2). There may also be intermolecular π–π interactions between adjacent pyridine rings, with a centroid-centroid distance of 3.796 (2) Å.

Experimental top

A solution of 1,4-diaminobutane (0.200 g, 2.269 mmol) and pyridine-2-carboxylic acid (1.173 g, 9.528 mmol) in H2O (20 ml) was stirred for 3 h at 60 °C. The solvent was removed under vacuum and the residue was washed with acetone/ether, to give a white powder (0.830 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from an acetone solution.

Refinement top

All H atoms were located from Fourier difference maps and refined isotropically; C—H = 0.91 (2)–1.05 (3) Å, N—H = 0.95 (3)–0.99 (3) Å and O—H = 0.92 (4) Å.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
