We report the synthesis, characterization, and solution self-assembly of plenary NbPW-based transition-metal substituted polyoxometalate, which is obtained by simply adding transition metals (Co) into aqueous solution containing cluster [(NbO)PWO], which is obtained by an in situ synthetic method. The incorporation of Co ions significantly affects the crystal structure, resulting in the formation of a 1D chain-like crystal and the first example of a niobotungstate-based cobalt derivative cluster. The behavior and stability of this cluster in solution are confirmed by time-resolved static light scattering, dynamic light scattering, small-angle X-ray scattering, and electrospray mass spectrometry studies.
我们报道了全同立构铌磷钨酸盐基过渡金属取代多金属氧酸盐的合成、表征及溶液自组装，该化合物是通过将过渡金属（钴）简单加入含有簇合物[(NbO)PWO]的水溶液中得到的，而[(NbO)PWO]是通过原位合成法获得的。钴离子的掺入显著影响晶体结构，导致形成一维链状晶体以及首个基于铌钨酸盐的钴衍生物簇合物。通过时间分辨静态光散射、动态光散射、小角X射线散射和电喷雾质谱研究证实了该簇合物在溶液中的行为和稳定性。
