Chemistry of the Group 1B metals. X. Reactions between silver arylacetylides and some rhodium(I) and iridium(I) complexes

Abstract

Reactions between AgC₂Ar (Ar = Ph or C₆F₅) and RhCl(PPh₃)₃ or IrCl(CO)(PPh₃)₂ have given hexanuclear heteroatom cluster compounds M₂Ag₄(C₂Ar)₈(PPh₃)₂ (M = Rh or Ir), and the zwitterionic complexes {[Ag(PPh₃)]⁺ [M(C₂C₆F₅)₄(PPh₃)₂]^-} and {[Ag(PPh₃)]₂⁺ [Rh(C₂C₆F₅)₅(PPh₃)] ^2-}.The structures of these complexes are described and discussed, together with possible reactions by which they may be formed.
