以苯并15冠5和钼多酸为原料, 用水热法合成了两个新颖的超分子配合物[Na(B30C10)][Mo6O19] (1)和[NaL(CH3CN)][NaL][α-PMo12O40][NaL2] (L＝B15C5) (2), 并用单晶X射线衍射测定了它们的晶体结构. 配合物1属单斜晶系, 空间群为C2/m, 它包含三个基本单元: Na＋, B15C5和Mo6O , 冠醚分子和Na＋配位, 并通过静电作用力和多酸分子相连. 配合物2属三斜晶系, 空间群为P-1, 它包含一个[α-PMo12O40]3－离子和三个钠离子配合物. [Na(B15C5)]＋通过Mo—O—Na—O键和多酸阴离子相连.

Two novel supramolecular complexes [Na(B30C10)][Mo6O19] (1) and [NaL(CH3CN)][NaL][α-PMo12O40][NaL2] (L＝B15C5) (2) were synthesized based on B15C5 and polymolybdates by hydrothermal techniques and characterized by X-ray diffraction analysis. Single crystal X-ray diffraction indicates that complex 1 belongs to monoclinic, C2/m, and consists of three basic units: Na＋, B15C5 and Mo6O . The crown ethers coordinate with Na＋, and connected with polyoxometalate by static force. Complex 2 crystallizes in the triclinic space group P-1 and contains an [α-PMo12O40]3－ anion and three sodium complexes, [Na(B15C5)]＋ connected through Mo—O—Na—O bond.
