在对苯二胺存在的条件下,通过水热方法得到了具有新结构的磷酸,相同条件下也得到了该材料的单晶体,并通过单晶X射线衍射解析其结构。新结构的磷酸锌属单斜晶系,P2,空间群,结构组成为Zn3(H2O)(PO4)2,晶胞参数M=404.07,a=0.8747(3)nm,b=0.4890(7)nm,c=1.6731(2)nm,β95.639(2)°,V=0.7122(7)nm^3,Z=4,Dc-=3.768g/cm^3。通过共用顶点连接的PO4四面体和ZnO4、ZnO3(H2O)六面体结构单元形成了Zn3(H2O)(PO4)2的三维开放骨架,而整个结构也可以看作是有三元环、四元环和八元环共同构成的。
A new structural zinc phosphate was prepared by hydrothermal method in the present of NH2 (C6 H4 )NH2. The single crystals were also obtained and their structures were solved by single-crystal X-ray diffraction. The new structural zinc phosphate with the composition of Zn3 (H2 O) (PO4)2 belongs to monoclinic crystalline system with P2..(No. 4) space group. Crystal data: M=404.07, a=0. 8747(3)nm, b=0.4890(7)nm, c=1.6731(2)nm, β=95.639(2)°, V= 0. 7122 (7) nm3, Z= 4, Dc = 3. 768 g/cm^3. Vertex linked PO4 tetrahedra and ZnO6, ZnO5 (H2 O) octahedra form the 3D open-framework of Zn3 (H2 O)(PO4 )2. The whole structure was constructed by 3-, 4- and 8- membered rings.
