Abstract

Crystalline phases of (triglyme)₁:LiX (X = CF₃SO ₃^-, BF₄^-, ClO₄ ^-, and AsF₆^-) have been isolated and structurally characterized. The phases are isostructural and represent a novel form of Li⁺ cation coordination not observed in crystalline poly(ethylene oxide) (PEO)-salt phases. The crystal structure of a (triglyme)₁:LiBPh₄ phase has also been determined, which differs markedly from those found with the smaller anions. In addition, a more concentrated (triglyme)_2/3:LiCF₃SO₃ phase has been characterized, which also displays a novel form of Li+ cation coordination. Such solvates represent models for interchain cation transport transition states in concentrated liquid and amorphous PEO electrolytes.
