(A) Crystal structure fragment of Li₂B₁₂H₁₂·2 diglyme and the approaches used for solvent removal; (B) PXRD (λ = 0.71073 Å) patterns; (C) FTIR spectroscopy spectra of Li₂B₁₂H₁₂·n diglyme and DMSO/DEF-substituted samples before and after drying at 200 °C under vacuum; (D) Crystal structure fragment of Li₂B₁₂H₁₂·1.5 monoglyme and the approaches used for solvent removal; (E) PXRD patterns (λ = 0.71073 Å); (F) FTIR spectra of Li₂B₁₂H₁₂·n DME, Li₂B₁₂H₁₂·n H₂O, and anhydrous Li₂B₁₂H₁₂ after heat treatment. Color code: Li (green), B (dark blue), H (light grey), O (red), C (dark grey). Li₂B₁₂H₁₂: Lithium dodecaborate; PXRD: powder X-ray diffraction; FTIR: Fourier transform infrared; DMSO: dimethyl sulfoxide; DEF: N, N-diethylformamide; DME: 1,2-dimethoxyethane.
