摘要：

From reactions involving M{N(SiMe(3))(2)}(3) (M = La, Pr, Eu) and hexafluoro-tertbutanol [(CF3)(2)MeCOH, hftb.H) the following compounds have been isolated: [La(hftb)(3)](n) (1), [La(hftb)(3)(NH3)](n) (2), [La-2(hftb)(6)(NH3)(4)] (3), [La(hftb)(3)(Et(2)O)(0.33)](n) (4), [Pr(hftb)(3)](n) (5), [Pr-2(hftb)(6)(NH3)(4)], (6), [EU(hftb)(3)](n) (7) and [Eu-2(hftb)(6)(NH3)(2)] (8). These compounds were characterized by elemental analyses and spectroscopic studies. The structure of [Pr-2(hftb)(6)(NH3)(4)] (6) was determined by single-crystal X-ray diffraction. The molecule is a centrosymmetric dimer with the praseodymium atoms in a distorted octahedral configuration. The ammonia ligands are cis to each other, one is trans to a terminal hftb group and the other is trans to a bridging hftb group.
