在温和的水热条件下，合成了两个新的有机模板亚磷酸锌[H3N(CH2)4NH3]·[ZN3(HPO3)4]·H2O(1)和[C3N2H5]2·[ZN3(HPO3)4](2)。用单晶X射线衍射法确定了它们的结构，并用FTIR、元素分析、电感耦合等离子体分析、粉末X射线衍射法和热重分析对其结构进行了表征。除了相同的阴离子骨架组成外，这两个相都是由严格交替的四面体和HPO3假金字塔组成，通过它们的顶点连接在一起，生成具有相交的8元和12元环通道的三维骨架，模板分子位于其中。化合物1属三斜晶系，空间群为P1，晶胞参数如下：a=7.7703(4)A；b=9.1499(4)A；c=14.4685(3)A；α=89.965(2)°；β=87.050(2)°；γ=65.332(2)°；V=65.332(7)A3；Z=2。
Two new organically templated zinc phosphites, [H3N(CH2)4NH3]·[Zn3(HPO3)4]·H2O (1) and [C3N2H5]2·[Zn3(HPO3)4] (2) have been synthesized under mild hydrothermal conditions. Their structures were determined by single-crystal X-ray diffraction and further characterized by FTIR, elemental analysis, inductively coupled plasma (ICP) analysis, powder X-ray diffraction, and thermogravimetric analysis. In addition to the same anionic framework compositions of [Zn3(HPO3)4]2-, both phases consist of strictly alternating ZnO4 tetrahedra and HPO3 pseudo-pyramids linked through their vertexes to generate the three-dimensional frameworks with intersecting 8- and 12-membered ring channels, where the template molecules reside. Compound 1 crystallizes in the triclinic system, space group P1 with the following cell parameters: a = 7.7703(4) A; b = 9.1499(4) A; c = 14.4685(3) A; α = 89.965(2)°; β = 87.050(2)°; γ = 65.332(2)°; V = 933.31(7) A3; Z = 2. Compound 2 crystallizes in the triclinic system, space group P1 with the...
