The nitridooxouranium cation NUO + has been prepared as a new isoelectronic homologue to the uranyl dication UO 2 2+ by a sequence of ionmolecule 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 UO 2 2+ is investigated by means of quasi‐relativistic density‐functional calculations.
