Easy access to the Wilkinson tris(tert-butylimido)nitridomanganate(VII) complex from commercially available starting materials

The synthesis of dark green, crystalline Li2[Mn(NtBu)3 N] ∙ LiCl(THF)2 in two steps from commercially available starting materials is described. Reaction of MnF3 with LiNHtBu and LiCl and subsequent workup represents an easy access to this historic complex. 1H NMR, absorption and FT-IR spectra, and single crystal X-ray diffraction data are reported and confirm the identity of the material.
