The reaction of Ln[N(SiMe3)2]3.LiCl(THF)3(Ln = Yb and Er) with N-confused tetraphenylporphyrin (H2NCTPP) followed by Na(L(OMe))(L(OMe)=(eta5-C5H5)Co[P(=O)(OMe)2]) gives (NCTPP)Ln(L(OMe)), whose X-ray structures exhibit an eta2 agostic interaction between the metal centre and the inner C-H bond of the NCTPP ligand.
Ln[N(SiMe₃)₂]₃·[LiCl(THF)₃]ₓ（Ln = Yb和Er）与N-混淆四苯基卟啉（H₂NCTPP）反应，随后与Na(L(OMe))（L(OMe)=(η⁵-C₅H₅)Co[P(=O)(OMe)₂]）反应，得到（NCTPP）Ln(L(OMe))，其X射线结构显示金属中心与NCTPP配体的内C-H键之间存在η²-agostic相互作用。
