The title compound, (C10H9N2)[Al(C7H3NO4)2]·3H2O or (2,2′-bipyH)[Al(pydc)2]·3H2O (where 2,2′-bipy is 2,2′-bipyridine and pydcH2 is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of aluminium(III) nitrate nonahydrate with pyridine-2,6-dicarboxylic acid and 2,2′-bipyridine in a 1:2:4 molar ratio in aqueous solution. This compound is composed of an anionic complex, [Al(pydc)2]−, a protonated 2,2′-bipyridine molecule as a counter-ion, (2,2′-bipyH)+, and three uncoordinated water molecules. The anion is a six-coordinate complex, with the AlIII atom in a distorted octahedral geometry coordinated by two tridentate pyridine-2,6-dicarboxylate groups. In the intermolecular O—H⋯O, N—H⋯O, N—H⋯N and C—H⋯O hydrogen bonds, π–π stacking between two aromatic rings [centroid–centroid distance = 3.827 (10) Å], and C=O⋯π stacking [with distances of 3.2311 (13), 3.4924 (14) and 3.5731 (13) Å], connect the various components to form a supramolecular structure.

A solution of Al(NO3)3.9H2O (187 mg, 0.5 mmol) in water (5 ml) was added to an aqueous solution of pyridine-2,6-dicarboxylic acid (167 mg, 1 mmol) and 2,2'-bipyridine (312 mg, 2 mmol) in water (10 ml) in a 1:2:4 molar ratio and refluxed for an hour. Colourless crystals of the title compound were obtained after allowing the mixture to stand for two months at room temperature
The H-atoms were included in calculated positions and treated as riding atoms: O—H = 0.85 Å and C—H = 0.95 Å with Uiso(H) = 1.2Ueq(parent O or C-atom).

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. |

Our research interests are centered on the preparation of water soluble proton transfer compounds as novel self assembled systems that can function as suitable ligands in the synthesis of metal complexes. In this regard, we have reported cases in which proton transfer from pyridine-2,6-dicarboxylic acid, pydcH2, and benzene-1,2,4,5-tetracarboxylicacid, btcH4, to propane-1,3-diamine (pn) and 1,10-phenanthroline, (phen), has occured. This work has resulted in the formation of some novel proton transfer compounds such as (pnH2)(pydc).(pydcH2).2.5H2O (Aghabozorg, Ghadermazi, Ramezanipour, 2006), (pnH2)2(btc).2H2O (Aghabozorg, et al., 2007) and (phenH)4(btcH3)2(btcH2) (Aghabozorg, Ghadermazi, Attar Gharamaleki, 2006). For more details and related literature see our recent review article (Aghabozorg, et al., 2008).
The molecular structure and the crystal packing diagram of the title compound, (2,2'-bipyH)[Al(pydc)2].3H2O, are shown in Figs. 1 and 2, respectively. The title compound is composed of an anionic complex, [Al(pydc)2]-, protonated 2,2'-bipyridine as a counter ion, (2,2'-bipyH)+, and three uncoordinated water molecules. The AlIII atom is six-coordinated by two pyridine-2,6-dicarboxylate, (pydc)2-, groups which act as a tridentate ligand through two O and one N atoms. The O5—Al1—O3 and O8—Al1—O2 angles (90.72 (5)° and 91.91 (5)°, repectively) and O5—Al1—O2—C1 and O5—Al1—O3—C7 torsion angles (-98.48 (10)° and 97.57 (10)°, respectively) show that these two (pydc)2- anions are almost perpendicular to one another. So the anionic complex has a distorted octahedral geometry around the AlIII atom. For balancing the anionic complex, a protonated 2,2'-bipyridinium cation, (2,2'-bipyH)+, is present. The O2—Al1—O3 [159.56 (5)°] and O5—Al1—O8 [159.66 (5)°] bond angles indicate that the four carboxylate groups of the two dianions are oriented in a flattened tetrahedral arrangement around the AlIII atom.
In the crystal structure of the title compound, the spaces between two layers of [Al(pydc)2]- anions are filled with (2,2'-bipyH)+ cations and water molecules (Fig. 3). An important feature of the title compound is the presence of π-π and C═O···π staking interactions. The π-π stacking between the aromatic rings of Cg1 (Cg1: N1/C2—C6) and Cg1 [-x, 1 - y, 1 - z], with distances of 3.8271 (10) Å , are observed in Fig. 4. The C═O···π stacking interactions between C1═ O1 and Cg1, C7═O4 and Cg2 [Cg2 centroid of ring N3/C15—C19] and C1═O1 and Cg3 [Cg3 centroid of ring N4/C20—C24] with O···π distances of 3.4924 (14) Å (1 - x, 1 - y, 1 - z), 3.2311 (13) Å (1 - x, 2 - y, 1 - z) and 3.5731 (15) Å (1 - x, 1 - y, 1 - z), respectively, are shown in Fig. 5. Intermolecular O—H···O, N—H···O, N—H···N and C—H···O hydrogen bonds, D···A ranging from 2.6497 (19) Å to 3.372 (2) Å (Table 1), appear to be effective in the stabilization of the crystal structure, resulting in the formation of an interesting supramolecular structure.
