Abstract:

An open-framework manganese(Ⅱ) phosphite, ??NH4??4[Mn4(PO3H)6](JIS-10), was synthesised via ionothermal method using 1-pentyl-3-methylimidazolium bromide([Pemim]Br) as the solvent and the proton conduction property of the crystal was studied. The proton conductivity of the as-synthesized JIS-10 is increased from 5.32×10-4 S/cm(7 d) to 1.065×10-3 S/cm(60 d) at 98% relative humidity, the saturation degree of absorbed water plays an important role in the enhancement of conductivity. While in an anhydrous atmosphere, JIS-10 hardly conducts electricity.

Key words: Ionothermal synthesis, Manganese phosphite open framework compound, Proton conduction
