Preparation of a Mg2+-containing MOF through ion exchange and its high ionic conductivity†
Abstract
We report, for the first time, the preparation and ionic conductivity of a Mg2+-containing metal–organic framework (MOF) having type A features, i.e., an anionic framework containing Mg2+ as the counter cation. We prepared Mg3[(MnMo6O18)2L] (L12− = C{C6H4CHNC(CH2O)3}412−) (MOF-688-Mg) through a simple ion exchange reaction, and it showed high ionic conductivity above 10−5 S cm−1 at 25 °C under MeCN vapor.
