Two new cantilever-type polyoxometalates Na(5)(NH(4)){V(IV)(Mo(2)O(6))CH(3)C(O)(PO(3))(2)}.13H(2)O (1) and (NH(4))(4){V(IV)(Mo(2)O(6))NH(3)CH(2)CH(2)CH(2)C(O)(PO(3))(2)}.6H(2)O (2) have been synthesized and characterized by IR spectroscopy, UV-visible spectroscopy, elemental analysis, TG analysis, XPS, (31)P NMR and single-crystal X-ray diffraction. The structure analysis reveals that the diphosphonate, hydroxyethylidene diphosphonic acid and alendronic acid as the scaffolds, have been grafted on the "S"-shaped polyoxoanions and respectively. The alkyl groups of the diphosphonates like arms hanged on the polyoxoanions form the cantilever-type polyoxometalates.
两种新型的悬垂型多金属氧酸盐 Na(5)(NH(4)){V(IV)(Mo(2)O(6))CH(3)C(O)(PO(3))(2)}.13H(2)O (1) 和 (NH(4))(4){V(IV)(Mo(2)O(6))NH(3)CH(2)CH(2)CH(2)C(O)(PO(3))(2)}.6H(2)O (2) 已经通过红外光谱、紫外-可见光谱、元素分析、热重分析、X 射线光电子能谱、(31)P NMR 和单晶 X 射线衍射进行了合成和表征。结构分析表明，膦酸酯、羟基亚乙基二膦酸和阿仑膦酸作为支架，分别接枝到“S”型多氧阴离子上。膦酸酯的烷基基团像臂一样悬挂在多氧阴离子上，形成悬垂型多金属氧酸盐。
