Structural investigation of crystalline and solution phases in N, N, NE, NE-tetramethylethylenediamine (TMEDA) with lithium triflate (LiCF3SO3) and sodium triflate (NaCF3CO3)
Article Abstract:
Single crystals of N, N, N', N'-tetramethylethylenediamine (TMEDA): lithium triflate (LiTf) and TMEDA: sodium triflate (NaTf) crystal (dimer) is isolated and characterized by X-ray diffraction, differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), and Raman techniques. Some striking similarities we found between TMEDA: NaTf crystal and several glyme: LiTf crystals; both TMEDA: LiTf and G2: LiTf crystallize as discrete dimers comprised of two cations, two anions and two solvent molecules.

Investigation of fundamental transport properties and thermodynamics in diglyme-salt solutions
Article Abstract:
Solutions of diglyme containing either lithium triflate or tetrabutylammonium triflate are calculated to study the ionic mobility, the thermodynamics of ionic association, and the structure of associated species. It is concluded that the concentration dependence of the molar conductivity is due in large part to the variation of the ion mobilities with concentration.

Molecular dynamics simulations and spectroscopic studies of amorphous tetraglyme (CH3O(CH2CH2O)(sub 4)CH3) and tetraglyme: LiCF3SO3 structures
Article Abstract:
Ionic aggregates become larger and aggregation becomes more extensive at 400K than at 300K. As a result, the tetraglyme chains adopt more extended confirmations in tetraglyme- LiCF3SO3 at 400K than at 300K.
