摘要：

Ln(CH2SiMe3)(3)(THF)(2) react with 1,3-di-iso-propyl-4,5dimethylimidazol-2-ylidene (ImMe(2)iPr(2)) yielding Ln(CH2SiMe3)(3)(THF)(ImMe(2)iPr(2)) (1, Ln = Er and 2, Ln = Lu). Reaction of I and 2 with an excess Of ImMe(2)iPr(2), results in the formation of the heteroleptic alkyllanthanide complexes Ln(CH2SiMe3)(3)(-)(lmMe(2)iPr(2))(2) (3, Ln = Er) and (4, Ln = Lu). The molecular structures of 1, 2, and 4 show a distorded trigonal bipyramidal arrangement around the lanthanide centers with two alkyl ligands and one carbene in the equatorial positions.
