摘要：
The interconversion of monomeric and mu-oxo and di(mu-oxo) dimeric nitridotechnetium(VI) species in solution has been studied by ESR and UV-Vis spectrophotometry. High acidity and the presence of coordinating anions favour the monomeric form. In very weakly coordinating acids the mu-oxo and di(mu-oxo) aquanitrido cations have been identified. (AsPh(4))(2)[{TcNX(2)}(2)(mu O)(2)] (X = Cl, Br) have been prepared and the chloro complex shown to be a useful starting material for the preparation of di(mu-oxo) dimers by substitution.
