Abstract

By reaction of the Lewis base NBu₄[Au(3,5-C₆F₃Cl₂)₂] and AgCF₃COO in the presence of NBu₄CF₃COO the heterometallic compound (NBu₄)₂[Au(3,5-C₆F₃Cl₂)₂Ag₄(CF₃COO)₅] (2) is obtained. The structure displays an unprecendented square pyramidal AuAg₄ arrangement built up through four Au⋯Ag closed-shell interactions and two Au–C–Ag 3c–2e⁻ bridges.
