我们报道了多Mo取代的Preyssler型磷钨酸盐[P5W30-xMoxO110Na(H2O)]14−的合成，其中掺入了不同量的H3PO4、Na2WO4和Na2MoO4的Moviathe水热反应；并通过 31P 核磁共振 (NMR)、傅里叶变换红外 (FT-IR)、元素分析、电喷雾电离质谱 (ESI-MS) 和循环伏安法进行表征。通过增加反应混合物中 Na2MoO4 的量，取代的 Mo 数量增加，并且在 [P5W30-xMoxO110Na(H2O)]14− 中，最多可以产生五取代的 Mo 取代物质，作为具有不同 Mo 数量和 Mo 位置的异构体的混合物。单晶X射线结构分析和密度泛函理论计算表明最合适的取代位置是带位置。
We report the synthesis of multi‐Mo‐substituted Preyssler‐type phosphotungstates, [P5W30‐xMoxO110Na(H2O)]14−, with different amounts of incorporated Moviathe hydrothermal reactions of H3PO4, Na2WO4, and Na2MoO4; and characterization by31P nuclear magnetic resonance (NMR), Fourier‐transform infrared (FT‐IR), elemental analysis, electrospray ionization‐mass spectrometry (ESI‐MS), and cyclic voltammetry. The number of substituted Mo increases by increasing the amount of Na2MoO4in the reaction mixture, and in the [P5W30‐xMoxO110Na(H2O)]14−, up to penta‐Mo‐substituted species can be produced as mixtures of isomers with different Mo numbers and Mo positions. Single crystal X‐ray structure analysis and density functional theory calculation indicate that the most suitable substitution position is the belt position.
