(Received 22 September 2009; accepted 1 October 2009; online 10 October 2009)

In the title compound, [Ag₃(C₈H₆N₃)₃], the asymmetric unit contains three silver cations and three depronated 5-(2-pyridyl)pyrazol-1-ide ligands. Each silver cation is chelated by one 5-(2-pyridyl)pyrazol-1-ide ligand, which also acts as a bridging ligand towards the next silver ion via the second pyrazole N atom. In summary, three silver cations and three deprotonated 3-(2-pyridyl)-1H-pyrazole ligands produce a macrocyclic trimeric coordination oligomer that exhibits an almost planar conformation (mean deviation 0.1483 Å). In addition, short non-bonding Ag⋯Ag interactions [3.127 (2) Å] are observed.

Comment top

Deprotonated 3-(2-pyridyl)pyrazole is a potentially tridentate ligands and it's derivatives have been widely used for the construction of supramolecular architectures by their ability of producing coordination compounds (Ward et al. 1998; 2001). As a continuation of these studies, we now report the crystal structure of the title complex.

As shown in figure 1, the asymmetric unit contains three silver cations and three depronated 5-(2-pyridyl)pyrazol-1-ide ligands. Each silver cation is chelated with one 5-(2-pyridyl)pyrazol-1-ide ligand, which in addition acts as a bridging ligand towards the next silver ion via the second pyrazole nitrogen.

In summary, three silver cations and three depronated 5-(2-pyridyl)pyrazol-1-ide ligands produce a macrocyclic trimeric coordination oligomer that exhibits an almost planar conformation. In addition, short non-bonding Ag-Ag interactions (3.127 (2) Å) are observed.

Experimental top

The synthesis of the title compound is performed in 25 ml Teflon-lined stainless steel vessels. Powdered 3-(2-pyridyl)pyrazole (1 mmol) together with silver nitrate (1 mmol) is heated to 170°C in 10 ml of a water/ethanol mixture (1:1) for 24 h. Colorless crystals were obtained after cooling to room temperature.

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.
