Abstract
The coordination of CO2 to Lewis bases is well-known; however, its binding to Lewis acids is much less common. The ligation of CO2 to a zinc-substituted Wells–Dawson type polyoxometalate yielded [(n-C8H17)4N]8[α2-P2W17O61Zn(CO2)], which was studied by variable temperature 1H NMR, 13C NMR, and 31P NMR spectroscopy from room temperature to 201 K. The spectra were analyzed in consideration of predicted “end-on” coordination, POM-Zn-O-C-O, and “side-on” coordination where in addition an adjacent basic oxygen atom in the polyoxometalate binds the carbon atom of CO2. After adding 2,4,6-trimethypyridine into the solution, a plausible adduct, POM-CO2-2,4,6-trimethypyridine, was observed.
