Contrary to a recent claim that the zwitterionic bis(diolato)silicate 1 exhibits remarkable hydrolytic stability at pH 7–8, a closer look at 29 Si and 13 C NMR spectroscopic data of 1 under various conditions (solvent, pH, concentration) reveals that hydrolysis products are the predominant species in solution.
