A trigonal-bipyramidal coordinated ytterbium(III) alkyl: tris(trimethylsilylmethyl)bis(tetrahydrofuran-O)ytterbium(III)

M. Niemeyer

Abstract: The title compound, [Yb(CH₂SiMe₃)₃(thf)₂] (thf is tetrahydrofuran, C₄H₈O), was obtained by direct synthesis from ICH₂SiMe₃ and Yb chips. The Yb atom shows a slightly distorted trigonal-bipyramidal environment formed by the C atoms of three alkyl ligands in equatorial positions (average Yb-C = 2.374  Å) and the O atoms of two tetrahydrofuran molecules (average Yb-O = 2.330  Å).
