摘要：

From reactions of M{N(SiMe(3))(2)}(3) (M = La, Pr, Eu) and (CF3)(2)MeCOH(hftb.H) in thf, the following thf complexes were obtained: [La(hftb)(3)(thf)(3)] (1), [Pr(hftb)(3)(thf)(2.5)] (2), and [Eu(hftb)(3)(thf)(3)] (3). Single crystal X-ray diffraction showed that (1) is an octahedral complex in the form of the facial isomer. Sublimation of(l), (2) and (3) caused loss of thf and mass spectra revealed the presence of dinuclear species of type [M(2)F(x)(hftb)(5-x)](+). Addition of diglyme to M(hftb)(3) gave [La(hftb)(3)(digly)(1.5)]. (4), [Pr(hftb)(3)(digly)(1.5)] (6) and [Eu(hftb)(3)(digly)] (8). Sublimation of (4) gave [La(hftb)(3)(digly)] (5) and of (6) gave [Pr(hftb)(3)(digly)] (7). The complexes (5), (7) and (8) all sublimed in vacuo without loss of coordinated diglyme and their mass spectra revealed the presence of diglyme-containing species [M(hftb)(2)(digly)](+) and [MF(hftb)(digly)](+).
