Not Unhydrolyzed at pH 8

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