摘要：
SMCl3 reacts with Me3SiCH2Li in THF yielding Sm(CH2SiMe3)(3)(THF)(3) (1). The single crystal X-ray structural analyses of 1, Er(CH2SiMe3)(3)(THF)(2) (2), Yb(CH2SiMe3)(3)(THF)(2) (3), and Lu(CH2SiMe3)(3)(THF)(2) (4) show the Sm atom in a facoctahedral coordination and the heavier lanthanides Er, Yb, and Lu trigonal bipyramidally coordinated with the three alkyl ligands in equatorial and two THF molecules in axial positions.
