【摘要】 以（NH₄）₆Mo₇O₂₄·4H₂O、Sb₂O₃和Sb₂O₅等为原料,利用常规水溶液法合成了一例结构新颖的含有混合价锑的杂多钼酸盐:[（CH3）4N]8Na41H17[（SbⅢ3O3）（SbⅤMo6O24）2]6·162H2O （1）,并通过元素分析、红外光谱、热重分析和X射线单晶衍射等分析手段对化合物1进行了表征。化合物1含有夹心型的多酸阴离子簇[（Sb3O3）（SbMo6O24）2]11-,并进一步通过Na+连接形成二维结构。此外,我们还研究了该化合物的变色性质。当该化合物的粉末被加热或氙灯（300 W）照射时,其颜色由淡黄色变为青黄色或棕褐色。更多还原

【Abstract】 A novel heteropolymolybdate containing mixed-valence antimony [（CH₃）₄ N]₈ Na₄₁H₁₇[（SbⅢ₃ O₃）(SbⅤMo₆ O₂₄)₂]₆·162H₂ O（1） has been successfully synthesized by reaction of（NH₄）₆ Mo₇ O₂₄·4 H₂ O, Sb₂ O₃ and Sb₂ O₅ in a conventional aqueous method. This structure was structurally characterized by single-crystal X-ray diffraction, TG analysis, PXRD and IR spectrum. The results show that compound 1 contains a sandwich polyoxoanion [（Sb3 O3）（SbMo6 O24）2]11-, and further forms a two-dimensional structure through Na+connection. In addition, compound 1 also exhibits intriguing allochroic properties. It can change color from yellowy to cyan yellow/sepia when heated or ir-radiated by Xe lamp（full wave-band, P=300 W）.
