We have synthesized a series of gold(I), gold(III) or silver(I) derivatives with ferrocenylmethylpyrazole (pzCH2Fc) as ligand. X-ray structure determination for [Au(C6F5)(pzCH2Fc)] reveals a linear geometry for the gold centre and association of the molecules in pairs through intermolecular gold(I)–gold(I) interactions of 3.1204(6) Å. These molecules are further assembled into chains and the chains into a 3D structure through several hydrogen bonds. [Ag(OTf)(pzCH2Fc)] (OTf = triflate) is a dimer with a distorted tetrahedral geometry at the silver(I) centre and the triflate acting as bridging ligand.
Graphical abstractWe described the synthesis of some gold(I), gold(III) or silver(I) complexes with ferrocenylmethylpyrazole (pzCH2Fc) as ligand. [Au(C6F5)(pzCH2Fc)] and [Ag(OTf)(pzCH2Fc)] (OTf = triflate) are dimers due to intermolecular gold(I)–gold(I) interactions or to the presence of bridging triflate ligands, respectively. The gold compound also forms chains through Au⋯H and H⋯F interactions that further assembles into a supramolecular array through other hydrogen bonds.Figure optionsDownload full-size imageDownload as PowerPoint slide
