An aqueous solution (10 ml) of 2,5-dichloro-4-amino-benzenesulfonic acid (0.121 g, 0.5 mmol) was added to solid Ag2CO3 (0.069 g, 0.25 mmol) and stirred for several minutes until no further CO2 was given off; pyridine (0.0395 g, 0.5 mmol) in methanol (5 ml) was then added and a white precipitate formed. The precipitate was dissolved by dropwise addition of an aqueous solution of NH3 (14 M). Crystals of (I) were obtained by evaporation of the solution for several days at room temperature.
All H atoms on C atoms were positioned geometrically and refined as riding, with C—H = 0.93 ° A and Uiso(H) = 1.2 or 1.5 times Ueq(C). The amino H atoms were located in a difference Fourier map and refined isotropically. The water H atoms were located in a difference Fourier map and refined with Uiso(H) = 1.5Ueq(O).
The structure of the title compound, (I) (Fig. 1), containing a pyridine molecule, three water molecules and 2,5-dichloro-4-amino-benzenesulfonate (L) anion is described. In (I), pyridine and water molecule are coordinated to the metal, resulting in a slightly distorted linear coordination geometry for Ag (Table 1). Atoms Ag1, N1 and O1W are almost linear and the angle of N1—Ag1—O1W is 172.07°. The Ag—Npyrindine and Ag—O1W distances are 2.148 (6)Å and 2.162 (5) Å, respectively; the Ag—Npyrindine distance is similar to the equivalent value in related compound (Li et al., 2006). 2,5-Dichloro-4-amino-benzenesulfonate anion does not coordinate with Ag atom, but acts as counterions..
In (I), the coordination ability of the oxygen atom of guest water molecule is evidently stronger than that of sulfonate group and the latter group does not coordinate to the Ag ion. Adjacent molecules of L are interconnected by strong O—H···O hydrogen-bonding interactions between uncoordinated sulfonate O atoms and uncoordinated water molecules (Table 2). Thus, the compound forms a one-dimensional anions chain through extensive intermolecular hydrogen bonding (Fig. 2).
The related compound, [Ag(HL3)(Pic)2] (HL3 = p-hydroxybenzenesulfonic acid, Pic = β-picoline), has a dimeric structure and each silver cation is coordinated by two nitrogen atoms from two different β-picoline ligands and two oxygen atoms from two HL3 anions with Ag—N distances of 2.168 (3) and 2.163 (3) Å (Li et al., 2006).

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 structure of the title compound, (I) (Fig. 1), containing a pyridine molecule, three water molecules and 2,5-dichloro-4-amino-benzenesulfonate (L) anion is described. In (I), pyridine and water molecule are coordinated to the metal, resulting in a slightly distorted linear coordination geometry for Ag (Table 1). Atoms Ag1, N1 and O1W are almost linear and the angle of N1—Ag1—O1W is 172.07°. The Ag—Npyrindine and Ag—O1W distances are 2.148 (6)Å and 2.162 (5) Å, respectively; the Ag—Npyrindine distance is similar to the equivalent value in related compound (Li et al., 2006). 2,5-Dichloro-4-amino-benzenesulfonate anion does not coordinate with Ag atom, but acts as counterions..
In (I), the coordination ability of the oxygen atom of guest water molecule is evidently stronger than that of sulfonate group and the latter group does not coordinate to the Ag ion. Adjacent molecules of L are interconnected by strong O—H···O hydrogen-bonding interactions between uncoordinated sulfonate O atoms and uncoordinated water molecules (Table 2). Thus, the compound forms a one-dimensional anions chain through extensive intermolecular hydrogen bonding (Fig. 2).
