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。
The crystal structure of the supramolecular compound C12N_2H_9_2 (C_ (12) N_2H_8) [SW_ (12) O_ (40)] was synthesized by hydrothermal method. The crystal structure was determined by elemental analysis and X-ray single crystal diffraction. The crystal is of the orthorhombic, P2 (1) 2 (1) 2 (1) space group with unit cell parameters of a = 12.0168 (3), b = 21.0534 (6) (?), V = 5713.1 (3) (?) ~ 3, α = β = γ = 90 °, Z = 4 and D_c = 3.977 mg · m -3 and was determined by IR and XRD The structural characterization was carried out and the thermal stability of the crystal was investigated by thermogravimetric analysis. The compound is composed of phenanthroline and Keggin structure [SW_ (12) O_ (40)] ~ (2-) anions and hydrogen bonding to form supramolecular compounds.
