摘　　要：利用中温水热方法合成了一种新颖的具有三维开放骨架结构的Zn3(PO4)2(H2O)4盐.并对其进行了红外光谱、元素分析、热重分析和单晶x射线衍射分析.结果表明,标题化合物晶体属于正交晶系;Pnma空间群,晶胞参数a=1.0602(2)nm,b=1.8218(4)nm,c=5.0434(10)nm,α=β=γ=90.00°,V=0.97410nm3,Z=4,R1=0.0278,wR2=0.0841,M=458.142.首先,四元环与八元环在平行于0,1,1方向形成二维层状结构,然后二维层沿1,0,0方向进一步形成三维开放骨架结构.Using moderate hot water to compound a novel Zn3(PO4) 2(H2O)4 salt with three-dimensional open cage construction,against which infrared spectrum,elemental analysis,thermogravimetric analysis and single crystal X-ray diffraction analysis were made.It is turned out that title compound crystal belongs to orthorhombic system;Pnma space groups,cell parameters a=1.0602(2)nm,b=1.8218(4)nm,c=5.0434(10)nm,α=β=γ= 90.00°,V=0.97410nm3,Z=4,R 1=0.0278,wR 2=0.0841,M=458.142.Firstly,four-membered ring and octatomic ring formed a two-dimensional layer structure in parallel to 0,1,1 direction,then the layer structure formed a three-dimensional open cage construction along 1,0,0 direction.
