文摘

The reaction of divalent (ArO)₂Sm(THF)₃ · THF with phenyl isocyanate directly gives a bimetallic complex [(ArO)₂(DME)SM]₂[μ-η⁴-(PhN)OCCO(NPh)] · 4THF (ArO = 2,6-di-tertbutyl-4-methylphenoxo) via one-electron reduction and coupling reactions. In this complex, the deprotonated N,N′-diphenyloxamide ligand bridges two units of (ArO)₂(DME)Sm with C(5)-C(5^*), Sm-N and Sm-O(1) bonds of 1.43(2), 2.549(8) and 2.318(7) Å, respectively.
