【摘要】 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,P21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．β=95．639(2)°．V=0．7122(7)nm3, Z=4,Dc=3．768 g／cm3。通过共用顶点连接的PO4四面体和ZnO6、ZnO5(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。更多还原

【Abstract】 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 (H2O)(PO4 )2 belongs to monoclinic crystalline system with P21(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/cm3. Vertex linked PO4 tetrahedra and ZnO6 , ZnO5(H2O) octahedra form the 3D open-framework of Zn3 (H2O)(PO4 )2. The whole structure was constructed by 3-, 4- and 8- membered rings.更多还原
