Synthesis and Structure of an Inorganic-organic Hybrid Zinc Phosphite

在水热条件下,以1,6-己二胺为模板剂合成了一个三维(3D)亚磷酸锌无机-有机杂化化合物(C6N2H16)0.5ZnHPO3(ZnHPO-CJ15),并对其单晶结构进行了解析.结果表明,ZnHPO-CJ15晶体属单斜晶系,P21/c空间群,a=1.19587(7)nm,b=0.82766(5)nm,c=0.77756(5)nm,α=90.00°,β=95.8370(10)°,γ=90.00°,V=0.76562(8)nm3,Z=1.ZnHPO-CJ15具有层柱状结构,其骨架结构是由ZnO3N四面体和HPO3假四面体连接构成的二维4×8元环网层结构,层与层之间由1,6-己二胺分子与Zn配位柱撑连接形成三维结构.

A 3D inorganic-organic hybrid zinc phosphite （C6 N2 H16 ） 0. 5 ZnHPO3（ZnHPO-CJ15） has been hy-drothermally synthesized. Crystal data for ZnHPO-CJ15 are as follows： monoclinic system, P21 / c space group, a =1. 19587 nm, b = 0. 82766（5） nm, c = 0. 77756（5） nm, α = 90. 00°, β = 95. 8370（10）°, γ =90. 00°, V=0. 76562（8） nm3 and Z =1. Single-crystal structure analysis reveals that the inorganic framework of ZnHPO-CJ15 is constructed by the connection of HPO3 pseudo-pyramids and ZnO3 N tetrahedral to form 2D layers with 4- and 8-rings. The 1,6-hexanediamine molecules act as the pillars to link the adjacent zinc phos-phite layers via N-Zn bonds to form 3D framework.
