Hexakis(isocyanide)metals, M(RNC)6 (M = Cr, Mo, W; R = 2,6-Me2C6H3, 2,4,6-Me3C6H2, 2,4-t-Bu2-6-MeC6H2, 2,4,6-t-Bu3C6H2 and t-Bu), were prepared by the reduction of a halide of chromium(III), molybdenum(IV), molybdenum(V) or tungsten(VI) with sodium amalgam in the presence of an isocyanide. An X-ray crystallographic study of Mo(2,6-Me2C6H3NC)6 · C6H6 revealed that the molybdenum atom is approximately

additional ligands at chromium, was synthesized from Me2Si(C5Me4)2Li2 and CrCl2(THF)x in the presence of 2,6-xylyl isocyanide. The crystalstructure of the complex was determined. The complex is paramagnetic and does not coordinate phosphines, phosphites, nitriles, amines, or acetylenes, but it reacts readily with 2,6-xylyl isocyanide to give mono- and diisocyanide complexes.
