Functional molecular inorganic-organic hybrids of lacunary polyoxometalates and organic ligands attract much attention for advanced material applications. However, the inherent instability of lacunary polyoxomolybdates hinders the synthesis of hybrids and their utilization. Herein, we present a viable approach for the synthesis of molecular hybrids of trivacant lacunary Keggin-type polyoxomolybdates and multidentate organic ligands including carboxylates and phosphonates, which is based on the use of a lacunary structure stabilized by removable pyridyl ligands as a starting material.

缺位多金属氧酸盐与有机配体形成的功能性分子无机-有机杂化物在先进材料应用方面备受关注。然而，缺位多钼酸盐固有的不稳定性阻碍了杂化物的合成及其应用。在此，我们提出了一种可行的方法来合成三缺位的缺位Keggin型多钼酸盐与包括羧酸盐和膦酸盐在内的多齿有机配体的分子杂化物，该方法基于使用由可去除的吡啶基配体稳定的缺位结构作为起始原料。
