Hexakis(isocyanide)metals, M(RNC)6 (M=Cr, Mo, W; R=2,6-Me2C6H4, 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-Me2C2H3NC)6*C6H6 revealed that the molybdenum atom is approximately octahedrally coordinated by six isocyanide ligands.
