The First Metal Cluster Containing a P_2O Ligand: (CO)_13Ru_4(μ _6,η ~2-P_2O)Ru_4(CO)_13

摘要

Clusters such as 1 are, like the inorganic pyrophosphates, the anhydrides of the corresponding phosphorus acids, in this case the hydroxyphos- phinidene clusters. We envisage the generation of several new classes of polynuclear anhydrides from clusters with μ_3-POH or μ_2-P(OH)_2 groups and are currently exploring this interesting area.
