Bis[bis(1H-imidazole-[kappa]N3)silver(I)] naphthalene-1,5-disulfonate

P. Liu and D.-S. Deng

Abstract top

The title compound, [Ag(C3H4N2)2]2(C10H6O6S2), exists in the form of isolated cations and anions with electrostatic interaction between them. The Ag atom is two-coordinated by the N atoms of two crystallographically independent imidazole molecules. The naphthalene-1,5-disulfonate anion is located on a crystallographic center of symmetry. The cations and anions are connected through intermolecular N-H...O hydrogen bonds.

Comment top

In the part of our recent investigations into the development of mixed inorganic–organic hybrid materials, we synthesized the silver sulfonate compound, which can be possess a potential wide chemical opportunity.

Sulfonate compounds have received much attention due to their potential application in chemical absorption and separation (Cai et al., 2004; Zhou et al., 2004; Liu et al., 2006). However, the weak coordination nature of SO3–group makes its coordination mode very flexible and sensitive to the chemical environment (Côté et al., 2003). Likewise, Ag+ ion is a notoriously pliant with respect to its coordination sphere. Thus, in silver sulfonates, various coordination modes are observed with coordination number ranging from two to nine (Côté et al., 2004; Dalrymple et al., 2002; Reddy et al., 2003; Shimizu et al., 1999). On the other hand, the coordination behavior of arene–sulfonates with transition metals can be peculiar in the presence of amino ligands (Chen et al., 2001; Cai et al., 2001; Chen et al., 2002).

The structure of the title compound, (I), is depicted in Fig. 1. There is one crystallographically independent Ag centre, coordinated by two nitrogen atoms from two different imidazole ligands with Ag—N1 = 2.1088 (19)Å and Ag—N2 = 2.109 (2) Å, respectively. The lesser contact distance Ag···O1 = 2.8185 (19)Å is longer than the reported Ag···O distance (Lian et al., 2007).

Cations and anions are connected through intermolecular N—H···O hydrogen bonds to form a linear tapes (N4—H4A···O2ii): N4···O2ii = 2.786 (3) Å, H4A···O2ii = 1.96Å and angle N4—H4A···O2ii = 160.7°, which run along the a–axis. The linear tapes are arranged in parallel fashion and further linked via hydrogen bonding between the coordinated imidazole molecules and the sulfonate oxygen atoms, thus leading to neutral extended two–dimensional sheets (N2—H2A···O3iii): N2···O3iii = 2.998 (3) Å, angle N2—H2A···O3iii = 129.8° and (N2—H2A···O3iv): N2···O3iv = 3.082 (3) Å, angle N2—H2A···O3iv = 148.6° as shown on Fig. 2 (symmetry codes: (ii) 1 + x, y, z); (iii) x - 2, y + 1, z; (iv) -x, 2 - y, 2 - z).

Experimental top

Disodium 1,5–naphthalene–disulfonate (0.33 g, 1 mmol) and imidazole (0.27 g, 4 mmol) were added to an aqueous solution of AgNO3 (0.32 g, 2 mmol) (10 ml). The result solution was stirred at 343 K for four hours in a water bath. After filtration, a clear solution was set aside to crystallize.

Refinement top

All H atoms were positioned geometrically and treated as riding, with C—H = 0.93 Å, N—H = 0.86 Å, respectively, and with Uiso(H) = 1.2Ueq(C or N)

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
