Hydrothermal routes to new sodium polytungstates
The new acidic sodium polytungstates, Na5[H7W12O42]·20H2O ( 1) and Na2[H10W12O42]·20H2O ( 2), have been synthesised under hydrothermal conditions where variations of pH and temperature allow control of the protonation of the [W12O42]12- cluster in the products. The polytungstate cluster, [HnW12O42](...
