Abstract

The reaction of Nd(BH4)3 · 3THF with decaborane-14 in diglyme at 85–90°C yields Nd(B11H14)3 · 4Dg. The duration of the reaction is 20 h. The molar ratio of Nd(BH4)3 · 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 · 4Dg is stable to 150°C and decomposes with an exotherm at 160–190°C. The IR spectrum of Nd(B11H14)3 · 4Dg in the region of B-H stretching vibrations contains an intense band at 2530 cm−1. The 11B {1H} NMR spectra of the synthesized compound in diglyme solutions contain signals of the tetradecahydro-nido-undecaborate anion B11H −14 (δ = -14.0, -15.6, and -16.5 ppm).
