摘要

以三(羟甲基)氨基甲烷(THAM),乙酸锰为主要原料,用常温挥发法合成一种新型金属有机框架材料[NaMn_4~Ⅲ(THAM)_2(OAC)_6(H_2O)_3]_n·nClO_4. X-单晶衍射分析测定其结构为三维网络,结晶于三斜晶系,P-1空间群,晶胞参数为a=0. 899 0(10) nm,b=0. 929 6(12) nm,c=1. 194 5(14)nm,α=98. 835(10)°,β=93. 256(9)°,γ=104. 345(11)°,V=0. 951 0(2) nm~3.乙酸根采用桥联模式将相邻的一维"Z"型Mn—O链连接成二维层,然后Na离子进一步连接相邻的二维层形成三维阳离子骨架,高氯酸根游离于孔道中平衡体系电荷.该化合物可以作为阴离子交换材料.
        In this paper,a novel metal organic framework material [NaMn_4~Ⅲ( THAM)_2( OAC)_6( H_2O)_3]_n·nClO_4 was synthesized by volatilization at room temperature using tri( hydroxymethyl) aminomethane(THAM) and manganese acetate as the main raw materials. X-ray single crystal diffraction analysis revealed that it was a three-dimensional structure and crystallized in the triclinic crystalline system,P-1 space group unit. The cell parameters were a = 0. 899 0( 10) nm,b = 0. 929 6( 12) nm,c = 1. 194 5( 14) nm,α = 98. 835( 10) °,β = 93. 256( 9) °,γ = 104. 345( 11) °,V = 0. 951 0( 2) nm~3. In the framework material, the acetate is used to connect the adjacent one-dimensional"Z"type Mn—O chain into a twodimensional layer by bridging mode. Then the Na ions connect the adjacent two-dimensional layers to form a three-dimensional cationic skeleton. The perchlorate located in the pore can balance the charge of the system. The compound can be used as an anion exchange material.
