Oxidation and coupling of β-diketiminate ligand in lanthanide complexes: Novel eight-nuclear lanthanide clusters with μ-, μ _3-Cl, and μ _4-O bridge

摘要

Two novel eight-nuclear lanthanide oxide and chloride clusters Ln _8(μ-η ~2-L ~4) _2(μ _3- Cl) _4(μ-Cl) _(10)(μ _4-O) _3(THF) _8 (Ln = Er(3), Dy(4); L ~4 = [OC{(Me)CN-2,6- ~iPrC _6H _3} _2] ~(2-)) have been synthesized by the reaction of β-diketiminate rare-earth metal chlorides with oxygen, providing a new oxidation and coupling reaction of the β-diketiminate ligand.
