[TcCl4(H2O)2] and [Cl3(H2O)2TcOTc(H2O)2Cl3]– two molecular intermediates of the hydrolysis of technetium(IV)

Two molecular intermediates of the hydrolysis of technetium tetrachloride, cis-[TcCl4(H2O)2] and [Cl3(H2O)2TcOTc(H2O)2Cl3], were isolated and structurally characterised, suggesting that the hydrolytic degradation of technetium(IV) compounds occurs stepwise with the polymeric ʹTcO2...nH2Oʹ as a less defined final product.
