cyclo-Tris[μ-5-(2-pyridyl)pyrazol-1-ido-κ3N1,N5:N2]trisilver(I)

Abstract

In the title compound, [Ag-3(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 angstrom). In addition, short non-bonding Ag center dot center dot center dot Ag interactions [3.127 (2) angstrom] are observed.
