Rea. Dillon et al., X-ray structure determinations of Li[CF3SO2N(CH2)(3)OCH3] and the solid electrolyte [Li subset of 12-C-4][CF3SO2N(CH2)(3)OCH3], CHEM MATER, 12(4), 2000, pp. 1122-1126
The crystal structures of the lithium salt, Li[CF3SO2N(CH2)(3)OCH3] and its
12-C-4 complex [Li subset of 12-C-4][CF3SO2N(CH2)(3)OCH3] demonstrate a ch
ange in the lithium coordination environment upon complex formation. The lo
nger Li-N bond distance in [Li subset of 12-C-4][CF3SO2N(CH2)(3)OCH3] indic
ates that the 12-C-4 crown ether weakens the interactions between the lithi
um cation and the [CF3SO2N(CH2)(3)OCH3](-) anion. Correlations between thes
e structures and previously reported vibrational spectroscopy and ionic con
ductivity are presented.
