Ionothermal synthesis of crystalline metal phosphites using multifunctional protic ionic liquids

Abstract

Two new crystalline metal phosphites (SCU-9 and SCU-17) were ionothermally prepared using multifunctional protic ionic liquids. SCU-9 has a three-dimensional structure containing both organic templates and organic ligands. SCU-17 is a mixed-valence compound with a layered structure templated by organic cations. This compound is resistant to hydrolysis in boiling water and shows interesting proton-conducting behaviors under 95% relative humidity.
