The structure of [1], determined by single crystal X-ray diffraction techniques, consists of corner sharing LiO4 and SO4 tetrahedra, forming an anionic 3-D open framework that is charge balanced by hydronium ions positioned within channels running along [001] and forming strong H-bonding with the framework oxygen atoms. Compound [1] undergoes two reversible phase transitions, involving reorientation of SO42- ions at pressures of approximately 2.5 and 5 GPa at room temperature, as evident from characteristic discontinuous frequency drops in the v(1) mode of the Raman spectra. Additionally, compound [1] forms dense beta-lithium sulfate at 300 degrees C, as evident from temperature dependent powder XRD and combined reversible TGA-DSC experiments. (C) 2012 Elsevier Inc.
