The 2-(3-pyridyl)benzimidazole was synthesized according to the literature (Alcalde et al., 1992). A solution of AgNO3 (0.104 g, 0.61 mmol), 2-(3-pyridyl)benzimidazole (0.14 g, 0.61 mmol), 1,3,5-benzenetricarboxylatic acid (0.128 g, 0.61 mmol) and H2O (15 ml) was stirred under ambient condition, adjust with dilute NaOH to pH=7.3, then sealed in Teflon-lined stainless steel vessel, heated at 403 K for 4 days and cooled to room temperature. The resulting product was recovered by filtration, washed with distilled water and dried in air. (60% yield).
After checking their presence in the different map, H atoms bonded to C and N were fixed geometrically and allowed to ride on their attached atoms, with C—H=0.93 Å, N—H=0.86 Å, Uiso(H)=1.2Ueq(C,N). The two carboxylic acid H atoms were located from a difference map and refined with a restraint of 0.83 (1)Å for the O—H distance.

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. |

1,3,5-Benzenetricarboxylatic acid has been often be used to construct supramolecular structures (Dai et al., 2003, Prior et al., 2003; Plater et al., 2001). In those coordination complexes, the 1,3,5-benzenetricarboxylatic acid ligand demonstrated versatile coordination modes and the tendence of forming hydrogen bonds. The structures are controlled by the extent of the depronation of 1,3,5-benzenetricarboxylatic acid, the nature of the auxiliary ligands, and the metal centers.
In the title compound each two AgI atom is bonded by two nitrogen atoms from two two 2-(3-pyridyl)benzimidazole ligands, forming a binuclear macrocycle. The coordination sphere is completed by a 3,5-dicarboxybenzoate ligand. The intermolecular N—H···O hydrogen bonding interactions connect the binuclear units into a two-dimensional undulating sheet with the protonated carboxylic acid groups on the opposite sides (Fig. 2). The sheets are further connected by O—H···O hydrogen bonding interactions into a three-dimensional framework (Fig. 3). Although there are aromatic rings, no apparent π···π stacking interactions have been found.
