Synthesis and Reactivity of Iso- and Hetero-Polyoxotungstates Containing Organic Subunits

The RCHMo$\sb4$O$\sb $H$\sp{3-}$(R = H, CH$\sb3$, CH$\sb2$CH) anions were prepared by reaction of Mo$\sb2$O$\sb7\sp{2-}$ with the appropriate aldehyde RCHO. The tungstate analogues RCHW$\sb4$O$\sb $H$\sp{3-}$ (R = H, CH$\sb3$, CH$\sb2$CH) were prepared by treatment of WO$\sb4\sp{2-}$ with the aldehyde in the presence of an equimolar amount of acids (e.g. HCl), and were isolated as pure crystalline solids. The spectroscopic data is consistent with all these anions being isostructural. The relative thermal stabilities of these compounds in CD$\sb3$CN solution were examined by measuring their $\sp1$H NMR spectra under several different conditions.
