Super Mg²⁺ Conductivity around 10^-3 S cm^-1 Observed in a Porous Metal-Organic Framework.

ABSTRACT: We first report a solid-state crystalline "Mg²⁺ conductor" showing a superionic conductivity of around 10^-3 S cm^-1 at ambient temperature, which was obtained using the pores of a metal-organic framework (MOF), MIL-101, as ion-conducting pathways. The MOF, MIL-101⊃{Mg(TFSI)₂}_1.6 (TFSI^- = bis(trifluoromethanesulfonyl)imide), containing Mg²⁺ inside its pores, showed a superionic conductivity of 1.9 × 10^-3 S cm^-1 at room temperature (RT) (25 °C) under the optimal guest vapor (MeCN), which is the highest value among all Mg²⁺-containing crystalline compounds. The Mg²⁺ conductivity in the MOF was estimated to be 0.8 × 10^-3 S cm^-1 at RT, by determining the
