The α‐Keggin ions [TNb 12 O 40 ] 16− (T=Si, Ge) have been synthesized hydrothermally as water‐soluble sodium salts. These clusters are very highly charged, and are bound to their charge‐balancing sodium atoms in the solid state (see picture). NMR spectroscopy experiments show that the sodium atoms remain strongly associated with the clusters in solution.
