【摘要】 利用常规合成方法合成了2个由2,2′-联咪唑修饰的Keggin型多金属氧酸盐有机-无机杂化化合物:[H3(biim)2](C4H8O2)2[PW12O40].11H2O(1)和[H3(biim)2](C4H8O2)3[PMo12O40].3H2O(2)(H2biim=2,2′-联咪唑),并通过单晶X射线衍射、元素分析、IR光谱和电化学分析等进行了表征.结构分析表明化合物1属于单斜晶系,C2/c空间群,化合物2属于正交晶系,Pbca空间群.分子间通过静电引力作用和氢键作用形成了三维超分子网状结构.更多还原

【Abstract】 Two organic-inorganic hybrid compounds constructed by 2,2′-biimidazole and Keggin-type polyoxometalate,[H3(biim)2](C4H8O2)2[PW12O40].11H2O(1)and[H3(biim)2](C4H8O2)3[PMo12O40].3H2O(2)(H2biim =2,2′-biimidazole)have been synthesized under routine synthetic method and characterized by single-crystal X ray diffraction,elemental analysis,IR spectroscopy and electrochemical analysis.The structural analysis shows that compound1 crystallizes in the monoclinic system,C2/c space group,and compound 2 crystallizes in the orthorhombic system,Pbca space group.The 3Dframeworks were built by the electrostatic forces and the extensive H-bonding interactions among molecules.更多还原
