X-ray Structure Determinations of Li[CF3SO2N(CH2)3OCH3] and the Solid Electrolyte [Li⊂12-C-4][CF3SO2N(CH2)3OCH3]

The crystal structures of the lithium salt, Li[CF3SO2N(CH2)3OCH3] and its 12-C-4 complex [Li⊂12-C-4][CF3SO2N(CH2)3OCH3] demonstrate a change in the lithium coordination environment upon complex formation. The longer Li−N bond distance in [Li⊂12-C-4][CF3SO2N(CH2)3OCH3] indicates that the 12-C-4 crown...

Zusammenfassung:	The crystal structures of the lithium salt, Li[CF3SO2N(CH2)3OCH3] and its 12-C-4 complex [Li⊂12-C-4][CF3SO2N(CH2)3OCH3] demonstrate a change in the lithium coordination environment upon complex formation. The longer Li−N bond distance in [Li⊂12-C-4][CF3SO2N(CH2)3OCH3] indicates that the 12-C-4 crown ether weakens the interactions between the lithium cation and the [CF3SO2N(CH2)3OCH3]- anion. Correlations between these structures and previously reported vibrational spectroscopy and ionic conductivity are presented.
