  the C4B8 compounds were found to have nonrigid stereochemistries; both the 11B and 13C NMR spectra of the “carbons apart” compounds consisted of single resonance peaks, indicating rapid atom equilibration on the NMR time scale. The “carbons adjacent” compounds showed 11B NMR spectra of six resonance peaks; each had a different chemical shift and peak-area ratio pattern. The 11B NMR spectra of the “carbons

  The reactions of nido-2-R-3-(Me3Si)-2,3-C2B4H6 (R = Me3Si, 1; R = Me, 2) with [eta(5)-2,4-(Me)(2)C5H5](3)M in a molar ratio of 1:1, in toluene at elevated temperature (70 degrees C), produced mixed-ligand dimeric lanthanacarboranes of the type [(eta(5)-2,4-(Me)(2)C5H5)(eta(5)-2-R-3-(Me3Si)-2,3-C2B4H4)M](2) (3, M = Y, R = Me3Si; 4, M = Y, R = Me; 5, M = Gd, R = Me3Si; 6, M = Gd, R = Me; 7, M = Tb, R = SiMe3; 8, M = Tb, R = Me; 9 M = Dy, R = Me3Si; 10, M = Dy, R = Me; 11, M = Ho, R = Me3Si; 12, M = Ho, R = Me; 13, M = Er, R = Me3Si; 14, M = Er, R = Me; 15, M = Tm, R = SiMe3; 16, M = Tm, R = Me; 17, M = Lu, R = Me3Si; 18, M = Lu, R = Me) as crystalline solids in 75-88% yields. All the compounds were characterized by IR spectroscopy and elemental analyses. While the diamagnetic species 3, 4, 17, and 18 were characterized by H-1, C-13, and B-11 NMR spectroscopy, compounds 3-8, 10, 12-14, and 18 were also characterized by single-crystal X-ray diffraction analyses. On the basis of the reactivity pattern and isolated products, an intramolecular H-transfer reaction mechanism is proposed for the formation of these species.
