High ionic conduction in a robust anionic metal-organic framework containing Mg 2+ under guest vapors.

We report on the synthesis and high ionic conductivity of a highly crystalline Mg 2+ -containing metal-organic framework (MOF) with Type A feature ( i.e. , anionic framework having Mg 2+ as a counter cation). We synthesized Mg[Zr(C 14 H 3 O 8 ) 2 ] (SU-102-Mg) through ion exchange reaction. SU-102-Mg showed a high ionic conductivity of 3.6 × 10 -5 S cm -1 (25 °C, under MeCN vapor).
