Rotation of coordinated acetylide ligands on the triangular surface of trinuclear heterometallic clusters

[[abstract]]The C2 hydrocarbyl ligands occupy a key position in the development of dinuclear, trinuclear, and polynuclear organometallic chemistry. This position results partially from the belief that the chemistry of the Cz hydrocarbyl ligands in the organometallic complexes is analogous tothat of small hydrocarbon intermediates adsorbed on metal surfaces. Among the many interesting properties of the C2 ligands is their mobility on the coordination sphere of the transition-metal complexes. Related studies on the C2 hydrocarbyl moieties have attracted the attention of manytheoretical and synthetic chemists.[[fileno]]2010302010175[[department]]化學
