在镱（III）配合物[yb4 (μ 2‐η 2: η 2‐Ph 2 N 2) 4 (μ 3‐PhN) 2 (thf) 4] 1中存在一个平面的yb4 N 4八元环，由两个μ 3‐苯基限制配体覆盖（在右边的结构中只显示了苯基取代基的ipso‐C‐原子）。1可以从萘和偶氮苯中获得，并且是类镧卤化物还原n2的模式物质。
A planar Yb 4 N 4 eight‐membered ring capped by two μ 3‐phenylimido ligands is present in the ytterbium (III) complex [Yb 4 (μ 2‐η 2: η 2‐Ph 2 N 2) 4 (μ 3‐PhN) 2 (thf) 4] 1 (in the structure on the right only the ipso‐C‐atoms of the phenyl substituents are shown). 1 is accessible from naphthaleneytterbium and azobenzene and is of interest as model substance for N 2 reduction by lanthanoid halides.
