ChemInform Abstract: Syntheses and Reactivity of Acetylide‐Containing Clusters of Group 1B Metals. Stepwise Syntheses of Trinuclear (Au2Cu(C2Ph)4)‐ and Pentanuclear (Au3Cu2(C2Ph)6)‐ and (Au3Ag2(C2Ph)6)‐ Clusters.

Abstract The pentanuclear cluster (IVa) is obtained from the equimolar reaction between the acetylide‐Au polymer (III) and a mixture of the bis(acetylide)aurate (I) and the polymeric Cu‐acetylide (II).
