Figure 2. Proton-coupled ¹¹B NMR spectra of reaction products: (A) solid precipitate and (B) filtrate after 24 h reaction at 120 °C in a Schlenk setup (5 mmol LiBH₄ + 27.5 mmol DMS·BH₃); (C) PXRD patterns of selected as-synthesized Li₂B₁₂H₁₂·n diglyme samples (λ = 0.71073 Å); (D) Proton-coupled ¹¹B NMR spectra of selected as-synthesized Li₂B₁₂H₁₂·n diglyme samples; (E) Yields of selected as-synthesized Li₂B₁₂H₁₂·n diglyme samples. ¹¹B NMR: ¹¹B nuclear magnetic resonance; LiBH₄: lithium borohydride; DMS·BH₃: borane dimethyl sulfide complex; PXRD: powder X-ray diffraction; Li₂B₁₂H₁₂: lithium dodecaborate.
