Iron promoted end-on dinitrogen-bridging in heterobimetallic complexes of uranium and lanthanides.

ABSTRACT: End-on binding of dinitrogen to low valent metal centres is common in transition metal chemistry but remains extremely rare in f-elements chemistry. In particular, heterobimetallic end-on N₂ bridged complexes of lanthanides are unprecedented despite their potential relevance in catalytic reduction of dinitrogen. Here we report the synthesis and characterization of a series of N₂ bridged heterobimetallic complexes of U(iii), Ln(iii) and Ln(ii) which were prepared by reacting the Fe dinitrogen complex [Fe(depe)₂(N₂)] (depe = 1,2-bis(diethylphosphino)-ethane), complex A with [M^III{N(SiMe₃)₂}₃] (M = U, Ce, Sm, Dy, Tm) and [Ln^II{N(SiMe₃)₂}₂], (Ln = Sm, Yb).
