| dc.description.abstract |
The thermal decomposition of anhydrous Pa[3 with combining macron] Li2B12H12 was studied in situ by high resolution synchrotron X-ray diffraction. A first-order phase transition can be observed at 355 °C where the unit cell volume expands by ca. 8.7%. The expanded β-Li2B12H12 polymorph simultaneously decomposes to a hydrogen poor γ-Li2B12H12−x phase. Expansion of the unit cell across the discontinuity is consistent with reorientational motion of B12H122− anions, and the presence of a frustrated Li+ lattice indicating Li ion conduction. | |
