“…While Li + favors tetrahedral coordination in many solvents, − the coordination number of Li + in organic carbonates has been postulated to be between 2 and 6. − ,− Considering all Li + –carbonate complexes with a Li + coordination in this range, only solvation complexes with 2, 3, 4, and 6 coordinated molecules should have a single IR active vibrational transition, which discards 5 as a possible coordination number. In addition, a solvation structure containing 6 carbonates should have two Raman active transitions besides the single IR active mode, while those containing 2, 3, or 4 carbonates should only have one additional Raman active transition .…”
