通过依赖于由四乙铵、四丙铵和四丁铵阳离子控制的簇间距离来研究混合价[MoV 2 MoVI 16 O54（SO 3）2] 6-四烷基铵盐的电导率。单晶的晶体学分析表明，簇间距离取决于抗衡阳离子上烷基的链长。此外，发现单晶的电导率依赖于温度和链长。混合价态聚氧乙烯酸盐（POM）簇被认为是钼青铜的分子颗粒，通过其使用单晶将开发高度有序的网络，其中POM相当小并且与胶体纳米结构相比具有良好的组织结构。
The electrical conductivity of mixed-valence [MoV2MoVI16O54(SO3)2]6− tetraalkylammonium salts was investigated through dependence on the inter-cluster distance that is controlled by tetraethylammonium, tetrapropylammonium, and tetrabutylammonium cations. The crystallographic analysis of single crystals revealed that the inter-cluster distances are dependent on the chain length of the alkyl groups on the counter cations. In addition, the electrical conductivities of the single crystals were found to be dependent on both temperature and chain length. Mixed-valence polyoxometalate (POM) clusters are considered to be a molecular particle of Mo bronze by which highly ordered networks will be developed using single crystals, where POMs are rather small and have a well-organized structure compared to colloidal nanostructures.
