The title compound, C3H12N22+·C7H3NO42−·H2O, contains one dicationic fragment, one dianionic fragment and one water mol­ecule. The two carboxyl­ate groups of the pyridine-2,3-dicarboxyl­ate (pydc2−) fragment are almost perpendicular to each other [dihedral angle 83.10 (8)°]. In the crystal structure, inter­molecular N—H...O, N—H...N, O—H...O and C—H...O hydrogen bonds and edge-to-face π–π stacking, together with ion pairing, are responsible for extending the structure in three dimensions, resulting in a supra­molecular network.

Comment top

Pyridinedicarboxylic acids are applied as proton donors in ion pairs, as ligands in coordination compounds, and as hydrogen donor or acceptor in hydrogen bondings. However, their metal complexes have interesting properties in biological systems (Mendoza-Diaz et al., 2005).

The molecule of the title compound, (I), contains one dicationic and one dianionic fragments and also one water molecule (Fig. 1). The bond lengths and angles are within normal ranges (Allen et al., 1987). The two carboxylate groups of (pydc)2– fragment are perpendicular to each other.

As can be seen from the packing diagram (Fig. 2), the intramolecular N—H···O and intermolecular N—H···O, N—H···N, O—H···O and C—H···O hydrogen bonds (Table 1) and edge to face π-π stacking together with ion pairing are responsible for expanding the structure in three dimension resulting in a supramolecular network.

The bond distances and angles of C–H···π stacking are 2.81 Å (H···π) and 136° (C–H···π), which are within normal range (Chandrasekhar et al., 2001). Another notable feature of the structure as shown in Fig. 2, is that the hydrogen bonds between water molecules, NH3+ tail of diamine and O atom of carboxylate group (i.e. two O5, two N3 and two O3 atoms and the related H atoms) form a 12-membered cyclic arrangement with a centre of symmetry in the middle of the ring.

Experimental top

The title compound was synthesized by adding pyridine-2,3-dicarboxylic acid (10 mmol) to propane-1,3-diamine (10 mmol) in tetrahydrofuran (40 ml), and refluxing it. After a while, a white precipitate was obtained which was recrystallized to colorless crystals suitable for X-ray analysis.

Refinement top

H atoms were positioned geometrically, with O—H = 0.82 Å (for OH2), N—H = 0.91 Å (for NH3) and C—H = 0.95 and 0.99 Å for aromatic and methylene H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C,O,N).

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.
