以LiTFSA和DMB为原料，按1：1的摩尔比合成了一种新的分子晶体Li{N（SO2 CF 3）（2）}（C6 H4（OCH 3）（2））（1）。1的单晶X-射线衍射研究表明，该化合物具有双核结构，五配位锂中心由TFSA阴离子桥接。交流阻抗测量表明，在环境温度下，通过1的微晶的离子导电通过跳跃机制发生。(C)2015爱思唯尔B. V.保留所有权利。
A novel molecular crystal, Li{N(SO2CF3)(2)}(C6H4(OCH3)(2)) (1), was synthesized by heating LiTFSA with DMB in 1:1 molar ratio. Single crystal x-ray diffraction study of 1 revealed that the compound possesses a dinuclear structure with five-coordinate lithium centers bridged by TFSA anions. AC impedance measurements showed that ionic conduction through the crystallites of 1 takes place via a hopping mechanism at ambient temperature. (C) 2015 Elsevier B.V. All rights reserved.
