摘要 利用中温水热技术,成功合成了一种新的过渡金属配合物双支撑的Keggin型钼磷杂多金属氧酸盐[Zn(2,2′-bipy)2]2[PMo11^ⅥMo^ⅤO40],并采用红外光谱、元素分析、单晶X射线衍射等进行了表征.结果表明:标题化合物的基本结构单元是由1个杂多阴离子[PMo11^ⅥMo^ⅤO40]^4-和2个[Zn(2,2′-bipy)2]^2+片段组成的双支撑构型;不同的结构单元之间通过氢键作用形成一维链状超分子结构;链间进一步通过分子间氢键构成二维层;该晶体属于单斜晶系,P21/n空间群;晶胞参数a=1.3587(3)nm,b=1.2073(2)nm,c=1.8932(4)nm,α=90.00°,β=93.15(3)°,γ=90.00°,V=3.100(9)nm3,Z=2,R1=0.0658,wR2=0.2023. A novel compound [Zn(2,2′-bipy)2]2[PMo11^ⅥMo^ⅤO40] has been synthesized. It is decorated by transition-metal complex bisupporting Keggin-type molybdenum phosphate under mild hydrothermal conditions and structurally characterized by IR, elemental analyses and single-crystal X-ray diffraction. The result indicates that the structure of the compound consists of one [PMo11^ⅥMo^ⅤO40]^4- heteropolyoxoanion and two [Zn(2,2′-bipy)2]^2 + fragments. Different basic building subunits formed the 1D chainlike supramolecular architectures via hydrogen bonds. Then the 1D chains extended to 2D layers with the same weak interactions. The compound crystallized in the monoclinic space group P21/n with a = 1. 358 7 (3) ran, b = 1.2073(2) nm, c=1.893 2 (4) nm,α= 90.00°,β=93.15 (3)°,γ=90.00°,V=3.100 (9) nm^3,Z=2, R1=0.065 8,wR2=0.202 3.
