摘　　要：利用水热方法合成了两种多金属氧酸盐.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,化合物1晶体属于三斜晶系,P-1空间群;化合物2晶体属于单斜晶系,P21/c空间群.化合物1和2分别为Wells-Dawson型基本结构单元与4,4'-bipy和bpp通过氢键和π-π堆积作用构成的超分子化合物.Two POMs have been synthesized under the hydrothermal condition and characterized by elemental analysis,IR,TG and the single crystal X-ray diffraction. The result shows that the compound 1 crystallized in the Triclinic space group P-1,with the parameters a = 1. 3238( 3) nm,b = 1. 3961( 3) nm,c = 2. 7269( 6) nm,α = 77. 724( 3) °,β = 84. 404( 3) °,γ = 68. 935( 3) °,V = 4. 5939( 18) nm^3,Z = 2,R_1=0. 0707,wR_2= 0. 1561,M = 5018. 02; and compound 2 crystallized in the Monoclinic space group P21/c,with the parameters a = 2. 0049( 4) nm,b = 2. 5997( 5) nm,c = 2. 4893( 9) nm,β = 126. 750( 19) °,α= γ = 90°,V = 5. 3861nm^3,Z = 4,R_1= 0. 0882,wR_2= 0. 1614,M = 5386. 11. Compounds 1 and 2 respectively Wells-Dawson,basic structure unit with 4,4'-bipy and bpp through hydrogen bonding and π-π accumulation effect of supramolecular compounds.
