“…To elucidate correlations between structural features on the molecular level for performance in future catalytical applications, additional characterization by single-crystal X-ray diffraction (XRD) was carried out. [22][23][24][25][26][27][28][29] Although several crystal structures of Keggin-type POMs are known, there is little literature for single crystals of Keggin-POMs in their protonated form, most likely due to the difficulty in crystallizing them. [28,29] Nevertheless, we were able to successfully analyze single crystals of five out of the six new POMs presented in this paper.…”

The crystals were obtained by slow evaporation of the solvent from an aqueous solution of the respective compound in a desiccator under reduced pressure.…”

Adjusting the RedOx activity of polyoxometalate catalysts is a key challenge for the catalysis of selective oxidation reactions. For this purpose, the possibility of influencing the RedOx potential by the introduction of an additional RedOx-active element was investigated. Thereby, Keggin-type polyoxometalates (POMs) with up to three different elements in the metal framework were created. An advanced and reproducible synthetic procedure to incorporate Mn II and additionally V V into Keggin-type heteropolyacids alongside comprehensive characterization of the new mole-cules is presented. The success of our syntheses was confirmed by vibrational spectroscopy (IR and Raman) and elemental analysis. Furthermore, the new compounds were analyzed by NMR spectroscopy to investigate the characteristics of the POMs in solution. The structures of successfully crystalized compounds were determined by single-crystal Xray diffraction. Moreover, all synthesized compounds were characterized using UV/Vis spectroscopy and electrochemical analysis to get further insights into the electronic transfer processes and redox potentials.
