文摘
This chapter describes the synthesis, structure, and reactivity of molecular rare earth hydride clusters consisting of the dihydride species “(L)LnH2” bearing one anionic supporting ligand per metal. Generally, hydrogenolysis of the dialkyl precursors [(L)LnR2] with H2 easily leads to formation of polynuclear rare earth hydride clusters through self-assembly of the resulting dihydride species. The molecular structure and reactivity of the hydride clusters are significantly influenced by both the bulkiness of the ancillary ligands and the size of the metal ions. Unique reactivities are observed with various substrates, including CO, CO2, H2, and unsaturated C–C and C–N bonds, because of the synergistic effects of the multiple metal-hydride sites.
