Preyssler‐Pope‐Jeannin Polyanions [NaP5W30O110]14– and [AgP5W30O110]14–: Microwave‐Assisted Synthesis, Structure, and Biological Activity

The Preyssler‐Pope‐Jeannin polyanion [NaP5W30O110]14– (1) was prepared by microwave‐assisted synthesis in only 2 h with a yield comparable to the reported hydrothermal procedure. The purity of 1 was confirmed by FT‐IR and multinuclear NMR (31P, 183W) analysis. The silver(I)‐containing analogue [AgP5...

Summary:The Preyssler‐Pope‐Jeannin polyanion [NaP5W30O110]14– (1) was prepared by microwave‐assisted synthesis in only 2 h with a yield comparable to the reported hydrothermal procedure. The purity of 1 was confirmed by FT‐IR and multinuclear NMR (31P, 183W) analysis. The silver(I)‐containing analogue [AgP5W30O110]14– (2) was also prepared by hydrothermal (6 d) as well as microwave‐based (2 h) procedures. Polyanion 2 was characterized in the solid state by FT‐IR, single‐crystal XRD, TGA, and elemental analysis and in solution by 31P and 183W NMR, and ESI‐MS. The antiproliferative activities against human cells as well as the antimicrobial properties towards Gram‐positive and Gram‐negative bacteria were comparatively evaluated for 1 and 2.
