In contrast to the re-examined system which appears to contain weakly hydrogen-bonded H2O rather than a genuine ⁺ cation, the salt-like precipitate NO3 is shown to be the first well-defined ⁺-derivative of adequate stability, the anion of which is not coordinated to the central metal.Ample evidence for the existense of similar, but mostly metastable precipitation products X and , respectively, (X = e.g.Cl, Br, I, ClO4, HCO2 including the replacement of H2O by NH3) is presented.Some interesting, common features of organo-uranium- and -tin-systems, R3M^IVX, are elucidated.
