摘要
利用水热法合成了超分子化合物(C_(12)N_2H_9)_2(C_(12)N_2H_8)[SW_(12)O_(40)],通过元素分析和X射线单晶衍射确定了其晶体结构,该晶体为正交晶系,P2(1)2(1)2(1)空间群,晶胞参数为a=12.0168(3)(?),b=21.0534(6)(?),c=22.5820(6)(?),V= 5713.1(3)(?)~3,α=β=γ=90°,Z=4,D_c=3.977mg·m^(-3),并通过IR和XRD进行了结构表征,采用热重分析研究了晶体的热稳定性。该化合物由邻菲罗林和Keggin结构[SW_(12)O_(40)]^(2-)阴离子组成,以氢键自组装成超分子结构化合物。
A supermolecule compound （ C12 N2 H9 ） 2 （ C 12 N 2 H8 ） [ SW 12 O40 ] was prepared by hydrothermal synthesis and the crystal structure was confirmed by elemental analysis and single crystal X -ray diffraction. The crystal system was orthorhombic , the space group of the crystal is P2（ 1 ）2（ 1 ） 2（ 1 ）, the unit cell parameter is a = 12. 0168（3 ）A^.,b =21. 0534（6）A^.,c = 22. 5820（6）A^., V=5713.1 （3）A^.3 , α=β=γ=90° ,Z = 4 ,Dc = 3. 977mg · m^-3 respectively. This compound was characterized by IR and XRD. The thermal stability was investigated by thermogravimetric analysis. The structure of the compound was consisted of Phen, [ SW12O40 ]^2- anion, which were connected with hydrogen bonds to form a supramolecular structure.
