Synthesis and Reduction of Bimetallic Methyl-Bridged Rare-Earth Metal Complexes, [(C5H4SiMe3)2Ln(μ-CH3)]2 (Ln = Y, Tb, Dy).
Ontology highlight
ABSTRACT: The complexes [Cp'2Ln(μ-CH3)]2, (Cp' = C5H4SiMe3; Ln = Y, Tb, Dy) were reduced to determine if these methyl-bridged complexes would form mixed valent 4f n 5d1 Ln(II)/4f n Ln(III) compounds or bimetallic 4f n 5d1 Ln(II) compounds containing 5d1-5d1 metal-metal bonds upon reduction. Reaction of the known bridged-chloride complexes, [Cp'2Ln(μ-Cl)]2, 1-Ln (Ln = Y, Tb, Dy), with MeLi forms the bridged-methyl complexes [Cp'2Ln(μ-CH3)]2, 2-Ln, which were crystallographically characterized for Tb and Dy.
