摘要
The nitridooxouranium cation NUO+ has been prepared as a new isoelectronic homologue to the uranyl dication UO22+ by a sequence of ion-molecule reactions starting from the atomic uranium cation U+. Collision-induced dissociation experiments and ligand-exchange reactions serve to unambiguously identify the ion as a species in which the uranium cation is formally inserted in the NO molecule. New thermochemical data for NUO+ and UN+ are given, and the stability of NUO+ with respect to UO22+ is investigated by means of quasi-relativistic density-functional calculations.
