Abstract:	Breaking the chain : Reaction of a zirconium hydrazinediide with organoazides gives 2‐pentazene‐1,4‐diyl complexes, such as Zr(N₂^TBSN_py){N(Ad)N₃NPh₂}] (C gray, N blue, Si green, Zr turquoise), by formal 2+3] cycloaddition. Bonding within the N₅ chain is investigated using density functional calculations. These complexes thermally eject N₂ to give side‐on bonded diazenides.
