Abstract

The new homoleptic rare earth compound [Y(C(SiHMe2)(3))(3)] (2) is prepared in 82% yield by salt metathesis of YCl3 and 3 equivalents of [KC(SiHMe2)(3)] (1); two beta-agostic Y center dot center dot center dot(H -Si) interactions are observed for each C(SiHMe2)(3) ligand in 2, giving six agostic interactions per yttrium(III) center.
