alternating ZnO4 tetrahedra and [HPO32−] pseudo-pyramid by sharing vertices. Each four-membered ring is capped by a [HPO32−] pseudo-pyramid. The 1,2-diammonium-propane template molecules are located above the eight-membered rings. Compound 2 crystallizes in the orthorhombic system, space group Pbcn with cell parameters: a=8.8754(14) Å, b=16.667(3) Å, c=13.864(2) Å, and Z=4. It is built up from three-dimensional
两种有机模板化亚磷酸锌,[CH 3 CH(NH 3)CH 2 NH 3 ]·[Zn 2(HPO 3)3 ]·H 2 O(1)和[H 3 N(CH 2)6 NH 3 ]·[ Zn 3(HPO 3)4 ](2)被水热合成并通过单晶X射线衍射表征。化合物1在单斜晶系系统中结晶,空间群P 2 1 / c具有单元参数:a= 9.9875(13),b= 10.3402(11),c= 14.4373(16),β= 102.093°,Z= 4。它具有层状结构和位于形成氢键的无机层之间的有机模板分子。由四,八元环组成的无机层是通过共享顶点由交替的ZnO 4四面体和[HPO 3 2- ]伪金字塔构成的。每个四元环被[HPO 3 2- ]伪金字塔封端。1,2-二铵丙烷模板分子位于八元环上方。化合物2在正交晶系,空间群Pbcn中结晶单元格参数为:a = 8.8754(14)Å,b = 16.667(3)Å,c =
