Comment top

Saccharin is a well known artificial sweetener and its deprotonated form, the saccharinate ion (sac), shows interesting ligation properties (Baran & Yilmaz 2006). Two different silver(I) complex of sac were reported by Weber et al. (1993) and Yilmaz et al. (2004). As part of our studies of mixed-ligand silver(I)-sac complexes with pyridine derivaties, the title compound (I) was prepared and characterized.

As shown in (Fig. 1), the AgI atom in (I) is coordinated by a sac ion and a neutral 3-aminopyridine ligand. The coordination geometry of the AgI atom is two-coordinate (linear) (Table 1). The shortest Ag···Ag distance between adjacent molecules in the crystal is 3.529 (2) Å which is considerably longer than the upper limit of 3.30 Å suggested for an argentophilic interaction in the silver(I) complexes (Jansen, 1987). Individual molecules are connected by N—H···O hydrogen bonds, involving the amine H atoms of 3-aminopyridine and the carbonyl and sulfonyl O atoms of the sac anion, thus forming a three-dimensional network (Table 2).

Experimental top

Na(sac).2H2O (0.24 g, 1 mmol) and 3-aminopyridine (0.09 g, 1 mmol) were added to a 20 ml solution of AgNO3 (0.17 g, 1 mmol) dissolved in a mixture of water and acetonitryl (1:1, v/v). The solution was stirred for an hour at room temperature. Colourless prisms of (I) were obtained after 3 days by slow evoparation of the solution at room temperature.

Refinement top

All hydrogen atoms were placed in idealized locations (C—H = 0.93 Å, N—H = 0.86 Å) and refined as riding with Uiso(H) = 1.2Ueq(parent atom).

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.
