Abstract

The coordination chemistry of the N-substituted arylamido ligands [N(R)(C₆H₃R′₂-2,6)] [R = SiMe ₃, R′ = Me (L¹); R = CH₂Bu^t, R′ = Pr^j (L²)] toward Fe^II and Co ^II ions was studied. The monoamido complexes [M(L¹)(Cl) (tmeda)] [M = Fe (1), Co (2)] react readily with MeLi, affording the mononuclear, paramagnetic iron(II) and cobalt(II) methyl-arylamido complexes [M(L¹)(Me)(tmeda)] [M = Fe (3), Co (4)]. Treatment of 2:1 [Li(L ²)(THF)₂]/FeCl₂ affords the unusual two-coordinate iron(II) bis(arylamide) [Fe(L²)₂] (5).
