In the title compound, 0.5C10H10N22+·PF6−·C10H8N2·2C7H7NO2·H2O, the cation is located on a center of symmetry. The is determined by a complex three-dimensional network of intermolecular O—H⋯O, O—H⋯N, N—H⋯N and N—H⋯F hydrogen bonds. π–π stacking interactions between neighboring pyridyl rings are also present; the centroid–centroid distance is 3.643 (5) Å. The hexafluoridophosphate anion is disordered over two positions with site-occupancy factors of ca 0.6 and 0.4.

4-Aminobenzoic acid (1 mmol, 0.137 g), 4,4'-bipyridine (1 mmol, 0.156 g) and sodium hexafluoridophosphate (1 mmol, 0.162 g) were dissolved in hot water with stirring. Colorless single crystals were obtained at room temperature by slow evaporation of the solvent over a period of several days.
The disordered perchlorate ion was refined over two sites, with refined occupancies of 0.625 (8) and 0.375 (9). The P···F and F···F distances were restrained to be 1.48 (1) and 2.10 (3) Å, respectively. Water H atoms were located in a difference Fourier map and refined with distance restraints of O—H = 0.86 Å and H···H = 1.39 Å. The H atom bound to the N5 nitrogen atom in the cation and the carboxylic H atoms were refined with distance restraints of N—H = 0.90 Å and O—H = 0.90 Å, respectively. All other H atoms were placed at calculated positions and treated as riding on the parent atoms, with C—H = 0.93 Å, N—H = 0.86 Å, and with Uiso(H) = 1.2Ueq(C, N).

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. |

Hydrogen-bonding interactions between ligands are specific and directional. In this context, 4-aminobenzoic acid and 4,4'-bipyridine are excellent candidates for the construction of three-dimensional network motifs, which form regular hydrogen bonds, functioning as both hydrogen-bond donor and acceptor (Hu et al., 2003; Yang et al., 2004). Recently, we obtained the title compound under hydrothermal conditions and report its crystal structure here.
In the title compound (Fig. 1), all bond lengths and angles are unexceptional. The 4,4'-bipyridinium cation, which is located on a center of symmetry, is, on both sides, a hydrogen bond donor to unprotonated molecules of 4,4'-bipyridine. These are, in turn, hydrogen bond acceptors for one of the two independent molecules of 4-aminobenzoic acid. Thus the two 4-aminobenzoic acid molecules, the 4,4'-bipyridine and 4,4'-bipyridinium cation are connected by hydrogen bonding interactions to form a linear centrosymmetric chain. Further each of these chains is connected with each of two other chains by O—H···O hydrogen bonds (Table 1), via the interstitial solvent water molecules and the other independent 4-aminobenzoic acid molecules, forming, in effect, infinite chains with each repeating unit of five molecules offset against the next unit by the width of the connecting (C7NH7O2)2.(H2O)2 unit. π-π stacking interactions (the centroid-centroid distance between neighboring pyridyl rings is 3.643 Å) connect these chains to produce a three-dimensional network motif (Fig. 2).
