锂盐Li[CF 3SO 2N（CH 2）3 OCH 3]及其12-C-4配合物[Li = 12-C-4][CF 3SO 2N（CH 2）3 OCH 3]的晶体结构表明，在配合物形成时锂配位环境发生了变化。[Li <$12-C-4][CF 3SO 2N（CH 2）3 OCH 3]中较长的Li−N键距表明12-C-4冠醚削弱了锂阳离子与[CF 3SO 2N（CH 2）3 OCH 3]-阴离子之间的相互作用。这些结构和以前报道的振动光谱和离子电导率之间的相关性。
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.
