trimethylsilyl azide or 1-adamantyl azide with the previously reported hydrazinediido complex [Zr(N2TBSNpy)(═NNPh2)(py)] (9) at ambient temperature resulted in the formation of the five-membered zirconaacacycles [Zr(N2TBSNpy)(NTMSN3NPh2)] (10) and [Zr(N2TBSNpy)(NAdN3NPh2)] (11). Complex 11 was thermally converted into the diazenido complex 12 via loss of 1 molar equiv of molecular N2. The direct formation of the
