摘要：
The reaction of Nd(BH4)(3)center dot 3THF with decaborane-14 in diglyme at 85-90 degrees C yields Nd(B11H14)(3)center dot 4Dg. The duration of the reaction is 20 h. The molar ratio of Nd(BH4)(3) center dot 3THF to B10H14 is is 1:3.5. The product is precipitated with heptane from a diglyme solution. The yield is 70%. In an inert atmosphere, Nd(B11H14)(3)center dot 4Dg is stable to 150 degrees C and decomposes with an exotherm at 160-190 degrees C. The IR spectrum of Nd(B11H14)(3)center dot 4Dg in the region of B-H stretching vibrations contains an intense band at 2530 cm(-1) stop. The B-11 {H-1} NMR spectra of the synthesized compound in diglyme solutions contain signals of the tetradecahydro-nido-undecaborate anion B11H14-(delta = -14.0, -15.6, and -16.5 ppm).
