The synthesis and crystal structure of a novel gold(I)–pyrazolate hexamer containing an 18-membered inorganic ring

Abstract

The reaction of ClAuPPh₃ with sodium 3,5-diphenylpyrazolate in tetrahydrofuran with added AgOCOPh yields hexakis(µ-3,5-diphenylpyrazolato-N,N′)-hexagold(I)(1), a compound with a novel 18-membered twisted ring and a fused-edge bi-tetrahedral grouping of gold atoms, as determined crystallographically.
