title: U(IV) and U(V) azide complexes supported by amide or aryloxide ligands.
abstract: The uranium(IV) azides [Li(THF)(3)](2)[U(OAr)(4)(N(3))(2)], Ar = 2,6-Me(2)C(6)H(3), and {[Na(THF)(4)][U[N(SiMe(3))(2)](3)(N(3))(2)]}(x) have been synthesised and structurally characterised. Oxidation of these complexes affords [Li(THF)(3)][U(OAr)(5)(N(3))] and U[N(SiMe(3))(2)](3)(N(3))(2), which are the first azides of U(V).
