An aqueous solution (9 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. 2,3-dimethylprazine (1 mmol) was then added and a precipitate was formed. The precipitate was dissolved by ammonium hydroxide. Crystals of were obtained by evaporation of the solution for several days at room temperature.
H atoms of C atoms were positioned geometrically (C—H = 0.93–0.96 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl. H atoms bonded to atom N3 were located in a difference map and refined freely, but with Uiso(H) = 1.5Ueq(N). The water H atoms were located from a difference map and refined freely with Uiso(H) = 1.5Ueq(O). Restraints were applied to the N—H and O—H distances.
Metal–organic coordination polymers have received much attention for their interesting structural features and potential application in optical devices, enantiomer separation, chiral synthesis and selective catalysis (Yaghi & Li, 1995). In particular, silver(I) sulfonates have attracted intense interest from chemists (Cote & Shimizu, 2003). So far, some silver(I) sulfonate compounds with nitrogen-based secondary ligands have been observed in the literature (Li et al., 2006). Herein, we present a new sulfonate coordination polymer, namely [Ag(dmp)(H2O)].L (I), where dmp = 2,3-dimethylprazine and HL = 4-amino-2,5-dichlorobenzenesulfonic acid.
In the title compound, the unique AgI ion is three-coordinated by two N atoms from two symmetry realted dmp ligands, and one water O atom in a distorted trigonal-planar geometry (Fig. 1). The Ag—N distance is similar to those in reported compounds (Liu et al., 2007). The dmp ligands bridge neighboring AgI ions to form a chain structure (Fig. 2). The L ligand acts as a counter anion. Finally, the O—H···O and N—H···O hydrogen bonds complete the structure.

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. |

Metal–organic coordination polymers have received much attention for their interesting structural features and potential application in optical devices, enantiomer separation, chiral synthesis and selective catalysis (Yaghi & Li, 1995). In particular, silver(I) sulfonates have attracted intense interest from chemists (Cote & Shimizu, 2003). So far, some silver(I) sulfonate compounds with nitrogen-based secondary ligands have been observed in the literature (Li et al., 2006). Herein, we present a new sulfonate coordination polymer, namely [Ag(dmp)(H2O)].L (I), where dmp = 2,3-dimethylprazine and HL = 4-amino-2,5-dichlorobenzenesulfonic acid.
In the title compound, the unique AgI ion is three-coordinated by two N atoms from two symmetry realted dmp ligands, and one water O atom in a distorted trigonal-planar geometry (Fig. 1). The Ag—N distance is similar to those in reported compounds (Liu et al., 2007). The dmp ligands bridge neighboring AgI ions to form a chain structure (Fig. 2). The L ligand acts as a counter anion. Finally, the O—H···O and N—H···O hydrogen bonds complete the structure.
