Popis:	Treatment of [W(CO)(MeC2Me)2(η-C5H5)][PF6] with ONMe3 in acetonitrile yields [W(NCMe)(MeC2Me)2(η-C5H5)][PF6] which undergoes irreversible reduction at a Pt electrode in THF. Sodium amalgam reduction of [W(NCMe) (MeC2Me)2(η-C5H5)][PF6] gives orange crystals of [W2(µ-σ,σ,η 2,η 2-C4Me4)2 (η-C5H5)2] X-ray studies on which reveal pairwise alkyne coupling and a novel bis(metallacyclopentadiene) structure.
