• Peroxohexatungstate
• Nonclassical framework
• Structure elucidation
• P-31 NMR

The nonclassical heteropolyoxotungstate [P3W6(O-2)(6)(OH)(2)O-22](7-) has been successfully synthesized and characterized well by various techniques such as FT-IR, UV/Vis, TGA, as well as elemental analysis. The single-crystal X-ray analysis reveals that the two {PW3(O-2)(3)(OH)O-9} subunits are linked together through a {PO4} group, forming a nonclassical type of phosphotungstate polyanionic framework. Furthermore, the solution behaviour of the title compound has been investigated by UV/Vis spectroscopy, electrospray ionization mass spectrometry and P-31 nuclear magnetic resonance spectroscopy.
