The monoamido complexes [M(L<sup>1</sup>)(Cl)(tmeda)] [M = Fe (<b>1</b>), Co (<b>2</b>)] react readily with MeLi, affording the mononuclear, paramagnetic iron(II) and cobalt(II) methyl−arylamido complexes [M(L<sup>1</sup>)(Me)(tmeda)] [M = Fe (<b>3</b>), Co (<b>4</b>)]. Treatment of 2:1 [Li(L<sup>2</sup>)(THF)<sub>2</sub>]/FeCl<sub>2</sub> affords the unusual two-coordinate iron(II) bis(arylamide) [Fe(L<sup>2</sup>)<sub>2</sub>] (<b>5</b>).
