Being highly unsaturated and able to donate from one to five electrons, acetylide ligands show a diversity of bonding possibilities in transition metal clusters. The study of molecular clusters with these ligands allows the processes of hydrocarbon C{sub 2} group transformation on the polymetal centers of a catalytic surface to be clarified. Previously, for the synthesis of acetylide derivatives of tri- and tetranuclear clusters the authors used an approach based on the interaction of mononuclear acetylide complexes with metal carbonyl clusters. In this paper, the synthesis of tetranuclear butterfly clusters from trinuclear acetylide clusters is described.
