Selective deprotonation of the amidinate ligand in lutetium dinitrogen complex [{Cp*{MeC(NPr)}Lu}(μ-η:η-N)][K(crypt)] (Cp* = (CMe), crypt = 2,2,2-cryptand) afforded the novel Cp*/enolamido lutetium dinitrogen complex [{Cp*{HCC(NPr)}Lu}(μ-η:η-N)K][K(crypt)]. Due to the skeleton tension, a further rearrangement was confirmed with the formation of [{Cp*K{HCC(NPr)}Cp*Lu}(μ-η:η-N)][K(crypt)].
