Several novel triol-ligands functionalized Anderson-Evans type polyoxotungstates, KNa[{HOCHC(CHO)}AlOWO], KNa[{HOCHC(CHO)}CrOWO], KNa[{HOCHC(CHO)}CoOWO], and KNa[{HCC(CHO)}CoOWO], were successfully synthesized and characterized, in which some of the central metal ions have never been found in the Anderson-type polyoxotungstates. The single crystal X-ray diffraction analysis indicated that the clusters were on a status, in which only one-side μ-O was protonated. This indicates that the three-protonated cluster is a common type of Anderson cluster aside zero-protonated (A-type) and six-protonated (B-type), which could be named as the T-type.
几种新型的三醇配体功能化的安德森-埃文斯型多金属氧酸盐，KNa[{HOCHC(CHO)}AlOWO]、KNa[{HOCHC(CHO)}CrOWO]、KNa[{HOCHC(CHO)}CoOWO]和KNa[{HCC(CHO)}CoOWO]，已成功合成并表征，其中一些中心金属离子在安德森型多金属氧酸盐中从未被发现。单晶X射线衍射分析表明，这些簇处于仅一侧的μ-O被质子化的状态。这表明三质子化簇是除零质子化（A型）和六质子化（B型）之外的安德森簇的一种常见类型，可命名为T型。
