(Received 14 November 2013; accepted 21 November 2013; online 27 November 2013)

In the title compound, [Ag2(C6H7N2O2S)2], the AgI atom is coordinated by two N atoms from two N-(pyridin-2-yl)methane­sulfonamidate anions in a slightly bent linear geometry [N—Ag—N = 166.03 (7)°]. The AgI atoms are bridged by the N-(pyridin-2-yl)methane­sulfonamidate anions, forming a centrosymmetric dinuclear mol­ecule, in which the Ag⋯Ag distance is 2.7072 (4) Å.

Synthesis and crystallization top

An aqueous solution (5.0 ml) of AgNO3 (1.0 mmol) was layered carefully over a methano­lic solution (5.0 ml) of N-(pyridin-2-yl)methansulfonamide (1.0 mmol) in a tube and kept it in the dark. Colourless crystals were obtained after several weeks. These were washed with methanol and collected in 78.6% yield.

Refinement top

H atoms were placed in idealized positions and constrained to ride on their parent atoms with C—H = 0.93 or 0.96 Å, Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for the others.

Results and discussion top

A series of complexes with the symmetric di(pyridyl/pyrimidyl)amide ligands (Hu et al., 2004; Hsu et al., 2008; Yeh et al., 2008; Tsai et al., 2010) and the asymmetric methyl-4-(pyridin-/pyrimidin-2-ylcarbamoyl)benzoate (Wu et al., 2011; Hsiao et al., 2012) or phosphinic amide (Yeh & Chen, 2011; Yeh et al., 2012) ligands that exhibit inter­esting structural types have been synthesized and structurally characterized. These pyridyl/pyrimidyl amide ligands coordinate to the metal centers through their pyridyl/pyrimidyl nitro­gen atoms and/or amide oxygen atoms and inter­act with each other through hydrogen bonds involving the amide groups. These inter­actions are important for molecular recognition and constructing supra­molecular arrays. .

In the title compound, [Ag(C6H7N2SO2)]2, the Ag+ cations are coordinated with one pyridyl N and one amido N atoms from twoN-(pyridin-2-yl)methane­sulfonamido (L-) anions forming a slightly bent geometry (Fig. 1). The Ag···Ag distance separated by the bridging L- group is 2.7072 (4) Å.

Special details top

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.
