Synthetic and structural studies of the cyclopentadienyl-free yttrium alkyl alkoxide and aryloxide complexes [(Me3Si)2CH]2y(μ-OCMe3) 2Li(THF) and[Me3SiCH2]2Y(OC6H 3tBu2-2,6)(THF)2

YCl3 reacts with 2 equiv of LiCH(SiMe3)2 and 2 equiv of LiOCMe3 in THF to form the dialkyl dialkoxide complex [(Me3Si)2CH]2Y(μ-OCMe3) 2Li(THF), 1. The yttrium in 1 is surrounded by a distorted tetrahedral arrangement of two terminal alkyl groups and two bridging alkoxide groups, and the coordination around lithium is trigonal planar. The reaction of YCl3 with 2 equiv of LiCH2SiMe3 and 1 equiv of LiOC6H3tBu2-2,6 in THF forms the neutral dialkyl aryloxide complex (Me3SiCH2)2Y(OC6H3 tBu2-2,6)(THF)2 2. The coordination geometry around yttrium in 2 is a distorted trigonal bipyramid with the THF groups in the apical positions.
