(Received 18 July 2008; accepted 22 July 2008; online 26 July 2008)

The asymmetric unit of the title compound, [Ag₂(C₁₄H₁₄N₄)₂](C₆H₄Cl₂NO₃S)₂·4H₂O, contains one-half of each of two independent dicationic units, two 4-amino-2,5-dichlorobenzenesulfonate anions and four water molecules. Each centrosymmetric dicationic unit has a dinuclear structure in which two Ag^I atoms are bridged by two 1,2-bis(1H-imidazol-1-ylmethyl)benzene ligands in a slightly distorted linear coordination geometry. The 4-amino-2,5-dichlorobenzenesulfonate anion does not coordinate with the Ag^I center, acting only as a counteranion. In the crystal structure, intermolecular O—H⋯O and N—H⋯O hydrogen bonds form a three-dimensional network.

Comment top

Ag^I complexes have shown versatility of their coordination geometry (Aakeröy & Beatty, 1998; Ma et al., 2005). Some silver(I) sulfonate compounds, modified by secondary nitrogen-based ligands, have been reported (Cote & Shimizu, 2004; Liu et al., 2007). Herein, we present a new silver-sulfonate complex, namely [Ag₂(IBI)₂]L₂.4H₂O, where IBI is 1,2-bis ((1H-imidazol-1-yl)methyl)benzene and L is 4-amino-2,5-dichlorobenzenesulfonic acid.

Selected bond distances and angles are listed in Table 1. The asymmetric unit of the title compound contains one-half each of two independent dicationic units, two 4-amino-2,5-dichlorobenzenesulfonate anions and four water molecules. Each Ag^I ion is two-coordinated by two N atoms from two IBI ligands, showing a slightly distorted linear geometry. The Ag—N bond distances are within the normal range observed in N-containing Ag^I complexes (Li et al., 2006; Feazell et al., 2006). The L anion does not coordinate with silver ion but acts as a counteranion.

N—H···O and O—H···O hydrogen bonds between water molecules and L ligands result in the formation of a three-dimensional supramolecular structure (Table 2).

Experimental top

An aqueous solution (10 ml) of 4-amino-2,5-dichlorobenzenesulfonic acid (1 mmol) was added to solid Ag₂CO₃ (0.5 mmol) and stirred for several minutes until no further CO₂ was given off. 1-(3-(1H-Imidazol-1-yl)methyl)benzyl)-1H-imidazole (1 mmol) was then added and a precipitate was formed. The precipitate was dissolved by ammonium hydroxide. Single crystals of the title compound were obtained by slow evaporation of the solution for 6 d at room temperature.

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.
