摘要：
A family of inorganic-organic hybrid solid materials has been assembled from presynthesized Organic decamethylcucurbit[5]uril (Me(10)Q[5]) macrocycles and the well-known inorganic polyoxometalate (POM) clusters. Three compounds, formulated [(Na-6(H2O)(11)(Me(10)Q[5])(2)]center dot[beta-H2O (1), [Na-4(H2O7)(7)(Me(10)Q[5])(2)]center dot[alpha-SiW12O40]center dot 20H(2)O (2) and [Na-4(H2O),(Me(10)Q[5])(2)]center dot[beta-SiW12O40]center dot 13H(2)O (3) are reported. In the molecular structures of the three compounds, versatile Keggin-type polyoxottingstate clusters were successfully assembled as inorganic building blocks to build hybrid materials with Me(10)Q[5]. Compound I comprises beta-Keggin-type iso-polyoxotungstate [H2W12O40] clusters and Me(10)Q[5]. Compound 2 contains alpha-Keggin-type [SiW12O40](4) heteropolyimions and Me(10)Q[5], whereas compound 3 is constructed from fi-Keggin-type heteropolyoxosilicotungstate clusters [SiW12O40](4-) and Me(10)Q[5]. All of the compounds feature train-like structural subunits based on central POM/alkali metal backbones and two side rows of parallel Me(10)Q[5] macrocycics.
