Five new gold acetylides, [AuCCR], with hydroxyl or amino functions in the organic radical R have been prepared. From these, nine phosphine complexes [(R3P)AuCCR] with R = Ph or Cy were synthesised. Reactions between the phosphine gold acetylides [(Ph3P)AuCCC(Me)(OH)Et] or [(Cy 3P)AuCCC(Me)(OH)Et] and the iron carbonyl cluster [Et 4N][Fe4N(CO)12] gave both neutral [(R 3P)AuFe4N(CO)12] and ionic compounds [(R 3P)2Au][Fe4N(CO)12]. Reaction with the penta-iron cluster [Et4N][Fe5N(CO)14] afforded [(R3P)2Au][Fe5N(CO)14], [(R3P)2Au][Fe4N(CO)12] and [(R 3P)AuFe4N(CO)12]. The gold-iron clusters were characterised with spectroscopic methods (IR, NMR and M?ssbauer) and in the case of [(Cy3P)AuFe4N(CO)12] a single-crystal X-ray analysis.
