摘要 利用常规合成技术,合成了一种新颖的稀土钼磷多金属氧酸盐超分子化合物[Nd(1)(DMF)5(H2O)3][Nd(2)(DMF)5(H2O)2][P2Mo18O62].2DMF.8H2O(DMF=N,N′-二甲基甲酰胺),并测定了其晶体结构.结果表明:化合物属于三斜晶系,空间群为P-1;晶胞参数a=1.432 8(3)nm,b=1.433 6(3)nm,c=3.212 3(6)nm,α=93.72°,β=93.71(3)°,γ=96.52°,V=6.524(2)nm3,Z=2,R1=0.130 8,wR2=0.302 5. An unprecedented rare-earth polyoxometalate supramolecular compound [Nd(1)(DMF)5(H2O)3][Nd(2)(DMF)5(H2O)2][P2Mo18O62]·2DMF·8H2O(DMF=N,N′-dimethylformamide)was synthesized under room temperature with water and organic mixed solution,and the crystal structure was determined.The compound crystallized in the triclinic space group P_-1 with a=1.432 8(3) nm,b=1.433 6(3) nm,c=3.212 3(6) nm,α=93.72°,β=93.71(3)°,γ =96.52°,V=6.524(2) nm3,Z=2,R1=0.130 8,wR2=0.302 5.
