摘要：

By reacting an aqueous solution of ammonium heptamolybdate with formic acid in the presence of hydrazinium sulfate at pH approximate to 4.2 the compound (NH4)(42)[(Mo72Mo60V)-Mo-VI-O-372(HCO2)(30)(H2O)(72)]. xHCO(2)Na . yH(2)O 1 (x approximate to 30, y approximate to 250) with spherically shaped stable cluster anions is obtained; owing to the spherical shape of the cluster-shell template, the anion 1a (with the small 'nondisturbing' bidentate HCO2- ligand) exhibits a remarkable overall 'onion-type' structure, thereby revealing also a novel type of inclusion: a hydrogen-bonded cluster with 'onion-type' structure, which suggests interesting aspects for a new type of supramolecular chemistry.
