New Characterization of V{N(SiMe3)(2)}(3): Reductions of Tris[bis(trimethylsilyl)amido]vanadium(III) and -chromium(III) To Afford the Reduced Metal(II) Anions [M{N(SiMe3)(2)}(3)](-) (M = V and Cr)

During the preparation of V{N(SiMe3)(2)}(3) (1), a discrepancy between the violet color that we observed and the brown color previously reported prompted further investigation of this compound. As a result, a new spectroscopic study and a full structural characterization are presented. The synthesis, spectroscopy, and structural characteristics of its reduced salt, [K(18-crown-6)(Et2O)(2)][V{N(SiMe3)(2)}(3)] (2), and its chromium congener, [K(18-crown-6)(Et2O)(2)][Cr{N(SiMe3)(2)}(3)] (3), are also described. The H-1 NMR spectra for 1-3 and Cr{N(SiMe3)(2)}(3) as well as their cyclic voltammograms are also reported.
