High ionic conduction in a robust anionic metal–organic framework containing Mg2+ under guest vapors

Abstract

We report on the synthesis and high ionic conductivity of a highly crystalline Mg²⁺-containing metal–organic framework (MOF) with Type A feature (i.e., anionic framework having Mg²⁺ as a counter cation). We synthesized Mg[Zr(C₁₄H₃O₈)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).
