An aqueous solution (8 ml) of 2-amino-5-chlorobenzenesulfonic acid (1 mmol) was added to solid Ag2CO3 (0.5 mmol) and stirred for several minutes until no further CO2 was given off. The 2,5-dimethylprazine (1 mmol) was then added and a precipitate was formed. The precipitate was dissolved by ammonium hydroxide. Crystals were obtained by evaporation of the solution for several days at room temperature.
H atoms bonded to N atom were located in a difference map and refined with distance restraints of N–H = 0.85±0.01 Å and H···H = 1.3±0.01 Å, and with Uiso(H) = 1.2Ueq(N). H atoms of C atoms were positioned geometrically (C—H = 0.93 Å) and refined as riding, with Uiso(H)=1.2Ueq(C). The methyl groups were allowed to rotate but not to tip.
The design and synthesis of silver(I) sulfonates have attracted intense interests of chemists (Cote & Shimizu, 2003). Generally, the structure motifs of most silver(I) sulfonates observed is a two-dimensional layer, which is similar to that of metal phosphonates (Liu et al., 2007). So far, some silver(I) sulfonate compounds modified by nitrogen-based secondary ligands have been reported (Li et al., 2006). Herein, we present a new sulfonate coordination polymer, namely [Ag(dmp)(L)] where dmp = 2,5-dimethylpyrazine and HL= 2-amino-5-chlorobenzenesulfonic acid.
In the title compound the AgI cation is four-coordinated by three N atoms from two different 2,5-dimethylprazine molecules and a –NH2 group of 2-amino-5-chlorobenzenesulfonate anion, and one sulfonate O atom (Fig. 1). The Ag—O (sulfonate) distance is near to that in a related compound (Liu et al., 2007). The dmp ligand links two neighboring AgI atoms, forming a chain structure. The L ligands are attached on one side of the chains in a chelating mode. Finally, the molecules are linked through N—H···O hydrogen bonds (Table 1).

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. |

The design and synthesis of silver(I) sulfonates have attracted intense interests of chemists (Cote & Shimizu, 2003). Generally, the structure motifs of most silver(I) sulfonates observed is a two-dimensional layer, which is similar to that of metal phosphonates (Liu et al., 2007). So far, some silver(I) sulfonate compounds modified by nitrogen-based secondary ligands have been reported (Li et al., 2006). Herein, we present a new sulfonate coordination polymer, namely [Ag(dmp)(L)] where dmp = 2,5-dimethylpyrazine and HL= 2-amino-5-chlorobenzenesulfonic acid.
In the title compound the AgI cation is four-coordinated by three N atoms from two different 2,5-dimethylprazine molecules and a –NH2 group of 2-amino-5-chlorobenzenesulfonate anion, and one sulfonate O atom (Fig. 1). The Ag—O (sulfonate) distance is near to that in a related compound (Liu et al., 2007). The dmp ligand links two neighboring AgI atoms, forming a chain structure. The L ligands are attached on one side of the chains in a chelating mode. Finally, the molecules are linked through N—H···O hydrogen bonds (Table 1).
