当重氮基乙酸乙酯或叠氮苯加到 Zr Ir 键上时，会形成完整的有机氮桥（例如 1；Cp= C 5 H 5，Cp*= C 5 Me 5）。重氮乙酸乙酯络合物是热稳定的，但加热苯基叠氮化物络合物 1 会导致 N 2 的一级损失并形成桥联苯基亚氨基络合物。
An intact organonitrogen bridge is formed when ethyl diazoacetate or phenyl azide add across a Zr Ir bond (for example, 1; Cp= C 5 H 5, Cp*= C 5 Me 5). The ethyl diazoacetate complex is thermally stable, but heating the phenyl azide complex 1 leads to first‐order loss of N 2 and formation of the bridging phenylimido complex.
