Abstract

The hydrothermal synthesis and single crystal structure of (CN₄H₇)₂·Zn₃(HPO₃)₄ are reported. This phase is built up from a network of vertex-linked ZnO₄ and HPO₃ building units encapsulating the extra-framework animoguanidinium cations. A new type of three-dimensional network for the inorganic component of the structure arises, which contains polyhedral 4-, 6-, 8-, 12- and 16-rings. There are close (∼3.6 Å), side-on, template–template contacts similar to those seen between pairs of guanidinium cations in molecular compounds. Crystal data: (CN₄H₇)₂·Zn₃(HPO₃)₄, M_r=666.30, monoclinic, space group P2₁/n (No. 14), a=10.2589 (4) Å, b=29.5851 (12) Å, c=13.7578 (5) Å, β=103.303 (1)°, V=4063.6 (5) Å³, Z=8, T=298 (2) K, R(F)=0.0399, wR(F²)=0.0792.

(CN4H7)2·Zn3(HPO3)4，三维框架锌磷酸酯:模板-模板合作的一个例子?

报道了(CN4H7)2·Zn3(HPO3)4的水热合成及其单晶结构。这一阶段由顶点连接的ZnO4和HPO3建筑单元网络构建而成，这些建筑单元封装了框架外的氨基胍阳离子。一种新型的由4-、6-、8-、12-和16-环多面体组成的无机结构的三维网络出现了。存在紧密的(~ 3.6 Å)、侧对、模板-模板接触，类似于分子化合物中胍离子对之间的接触。晶体数据:(CN4H7)2·Zn3(HPO3)4, Mr=666.30，单斜，空间群P21/n (No. 14)， a=10.2589 (4) Å， b=29.5851 (12) Å， c=13.7578 (5) Å， β=103.303(1)°，V=4063.6 (5) Å3, Z=8, T=298 (2) K, R(F)=0.0399, wR(F2)=0.0792。
