A solution of Ag2O (0.07 g, 0.30 mmol), 2-(3-pyridyl)benzimidazole (Alcade et al., 1992) (0.14 g, 0.61 mmol) 4-sulfobenzoic acid (0.06 g, 0.30 mmol) and H2O (15 ml) was stirred under ambient condition and then sealed in teflon-lined stainless steel vessel, heated at 403 K for 4 days and cooled to room temperature for 3 days, creating the colorless crystals of the title compound.
All H atoms were fixed geometrically and allowed to ride on their attached atoms with C—H=0.93 Å, N—H=0.86 Å and U(H) = 1.2 Ueq(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. |

4-sulfobenzoic acid is an efficient O donor ligand, exhibiting versatile coordination mode and hydrogen bonding interaction in the assembly of metal-organic coordination polymers (Yuan et al., 2001), 4-sulfobenzoic acid could be in situ synthesized into benzene-1,4-disulfonate (Xiong et al., 2001). 2-(3-pyridyl)benzimidazole has been reported to connect the AgI ions, resulting in a binuclear macrocyclic (Su et al., 1999). Herein, we report the synthesis and structure of the coordination polymer on the basis of bridging benzene-1,4-disulfonate ligands and [Ag2(C12H9N3)2] binuclear units.
In the title compound, AgI exhibits a distorted trigonal planar geometry (Fig. 1). Each two AgI atoms are connected with two 2-(3-pyridyl)benzimidazole ligands in the end to end mode via Npy and NBIm donor atoms, forming a binuclear macrocyclic. The coordination sphere of AgI is completed by an oxygen atom from benzene-1,4-disulfonate with bis(monodentate) coordination fashion. The bridging benzene-1,4-disulfonate ligands link the binuclear units, forming a chain (Fig. 2). The chains are assembled into a two-dimensional network by the N—H···O hydrogen bonds as well as π-π interactions between the benzimidazolyl rings of 2-(3-pyridyl)benzimidazole ligands (the perpendicular distance is about 3.43 Å) (Fig. 3). The crystal packing can be viewed as layered arrangement of the two-dimensional supramolecular networks (Fig. 4).
