title: Assembly of an R3N5(2-) chain by cycloaddition of a hydrazinediide and an azide at zirconium and its thermal fragmentation.
abstract: Breaking the chain: Reaction of a zirconium hydrazinediide with organoazides gives 2-pentazene-1,4-diyl complexes, such as [Zr(N(2) (TBS)N(py)){N(Ad)N(3)NPh(2)}] (C gray, N blue, Si green, Zr turquoise), by formal [2+3] cycloaddition. Bonding within the N(5) chain is investigated using density functional calculations. These complexes thermally eject N(2) to give side-on bonded diazenides.
