Three-co-ordinated transition metal compounds. Part I. The preparation and characterization of tris(bistrimethylsilylamido)-derivatives of scandium, titanium, vanadium, chromium, and iron

Abstract

The compounds M[N(SiMe₃)₂]₃, where M = Sc, Ti, V, Cr, and Fe, have been prepared by reactions involving metal chloride complexes and the lithium derivative of hexamethyldisilazane. The compounds have been characterized by analysis, molecular weight determination, i.r., and mass spectra. They are members of a trigonally co-ordinated transition metal series.
