无机-有机杂化金属磷酸氢盐，式为（C2 H10 N2）[Mn 2（HPO 4）3]（H2O）（1），具有层状晶体结构。无机阴离子层由Mn 3 O 13簇单元构成，层间空间由电荷补偿的乙二胺二铵二价阳离子和晶格水分子填充。通过热重分析、变温粉末X射线衍射、无水和潮湿环境下的质子电导率研究，发现1具有很高的热稳定性和质子传输性能，在99%RH下293 K时的质子电导率达到1.64 × 10（-3）S·cm（-1）。高质子导电性与晶格中形成更致密的氢键网络有关。
The inorganic-organic hybrid metal hydrogenophosphate with a formula of (C2H10N2)[Mn2(HPO4)3](H2O) (1) shows layered crystal structure. The inorganic anion layer is built from Mn3O13 cluster units, and the interlayer spaces are filled by the charge-compensated ethylenediammonium dications together with the lattice water molecules. The thermogravimetry, variable-temperature powder X-ray diffraction, and the proton conductance under anhydrous and moisture environments were investigated for 1, disclosing that 1 shows high thermal stability and high proton transport nature, and the proton conductivity reaches to 1.64 × 10(-3) S·cm(-1) under 99%RH even at 293 K. The high proton conductivity is related to the formation of denser H-bond networks in the lattice.
