[Bi6O4(OH)(4)](NO3)(6)中心点H2O与三羧酸反应，由乙腈/氯仿结晶得到[Bi6O4(OH)(4)(OTf)(6)(CH3CN)(6)]中心点2CH(3)CN(1)的无色单晶。化合物1在单斜空间群P2(1)/n中结晶。该新型六核氧化铋团簇在水和极性有机溶剂中高度可溶。以[Bi6O4(OH)(4)(OTf)(6)(CH3CN)(6)]中心点2CH(3)CN(1)为原料，在水溶液中与聚丙烯酸酯反应，制得透明水溶性杂化材料。通过分子动力学模拟研究了[Bi6O4+x(OH)(4-x)]（(6-x)+）阳离子与聚丙烯酸酯在溶液中的络合行为。
The reaction of [Bi6O4(OH)(4)](NO3)(6)center dot H2O with triflic acid gave colorless single crystals of [Bi6O4(OH)(4)(OTf)(6)(CH3CN)(6)]center dot 2CH(3)CN (1) upon crystallization from acetonitrile/chloroform. Compound 1 crystallizes in the monoclinic space group P2(1)/n. The novel hexanuclear bismuth oxido cluster is highly soluble in water and polar organic solvents. A transparent and water-soluble hybrid material was obtained by reaction of [Bi6O4(OH)(4)(OTf)(6)(CH3CN)(6)]center dot 2CH(3)CN (1) with polyacrylate in aqueous solution. Molecular dynamics simulations were performed to study the complexation behavior of the [Bi6O4+x(OH)(4-x)]((6-x)+) cation with polyacrylate in solution.
