The First β-Diketiminato Complex of Terbium Containing Two Alkyl Groups: A Model Compound for LLnR₂(Ln = Lanthanide, R = Alkyl) Systems

Abstract

Reaction of a new β-diketiminato derivative of terbium, LTbBr2 (L = [N,N‘ ‘-(1,3-dimethyl-1,3-propanediylidene)bis[N‘,N‘-diethyl-1,2-ethanediamine]]), in the molar ratio 1:2 with LiCH2SiMe3 gives the terbium complex LTb(CH2SiMe3)2, whose structure was established by elemental and X-ray analyses.
