Z. An and R.-J. Zhou

Abstract: 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 AgAg interactions [3.127 (2) Å] are observed.
