The title compound crystallizes in the monoclinic space group P21/n, with a = 9.7904（11）, b = 14.0287（14）, c = 11.8651（13） A, β= 104.690（3）°, V= 1576.4（3） A^3, Z= 4, T= 296（2） K, Mr = 601.31 and Dc = 2.533 g/cm^3. The compound consists of a macroanionic [Zn3（OH2）（PO4）2（HPO4）]^2- framework and （C5N2H14）^2＋ cations, and its structure is built up from ZnO3（OH2）, ZnO4, HPO4 and PO4 tetrahedral units that result in 4, 8 and 10-ring channels.展开更多
