N2 - The reaction of one equivalent of Cp*2UCl2 with 2-(trimethylsilylimino)-1,3-di-tertbutylimidazoline in boiling toluene afforded a one electron oxidation of the uranium metal and the opening of the N-heterocyclic ring, resulting in the formation of an organometallic uranium(V) imine complex. This complex crystallized with one molecule of toluene in the unit cell, and its solid-state structurewas determined byX-ray diffraction analysis.When the same reaction was performed in perdeuterated toluene, a myriad of organometallic complexeswere obtained, however,when equimolaramounts ofwaterwere used in toluene, the same complex was obtained, and its solid state characterization shows two independent molecules inthe unit cellwithanadditionalwatermolecule. For comparison of the geometric parameters, the corresponding isolobal anionic uranium(IV) complex [Cp* 2UCl3]- was synthesized by the reaction of Cp*2UCl2 with 1,3-di-tert-butylimidazolium chloride, and the resulting U(IV)-ate complex was characterized by X-ray diffraction analysis.
