The effects of countercations and coexisting compounds on the molecular structure of the [M(α-PWO)] polyanion were analyzed in terms of the repulsion and twisting of two [α-PWO] units. More specifically, it was found that two [α-PWO] ions approached one another upon reducing the ionic radius of M in [M(α-PWO)] . The interactive twisting of the [α-PWO] units prevented mutual repulsion of the units containing terminal O atoms, and the tendency for approach and twisting of the [α-PWO] units varied as a function of the type of countercation and the presence of coexisting compounds. Overall, this study demonstrated that some interactions between the counteraction and coexisting compounds with [M(α-PWO)] determined the molecular conformation and the isolated form of the polyanion.
根据两个[α-PWO]单元的排斥和扭曲作用，分析了抗衡阳离子和共存化合物对[M(α-PWO)]聚阴离子分子结构的影响。更具体地说，发现在[M(α-PWO)]中减小M的离子半径时，两个[α-PWO]离子会相互靠近。[α-PWO]单元的相互作用扭曲阻止了含末端O原子单元之间的相互排斥，并且[α-PWO]单元的靠近和扭曲趋势随抗衡阳离子类型和共存化合物的存在而变化。总体而言，该研究表明抗衡离子和共存化合物与[M(α-PWO)]之间的某些相互作用决定了聚阴离子的分子构象和分离形式。
