摘要
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 129-,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）][α-PMo12O40]（L=B15C5）（2） were synthesized based on B15C5 and polymo-lybdates 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.
