Ru(C⋮CRc)(dppe)(η5-C9H7), and Ru(C⋮CRc‘)(dppe)(η5-C9H7) were determined by X-ray analysis. Cyclic voltammetry of the acetylide complexes showed two well-separated quasi-reversible waves. Chemical oxidation of ruthenium(II) 2,3,4,5-tetramethylruthenocenylacetylide complexes gave products whose stability was dependent on the ligand on the Ru(II) moiety. The 13C NMR spectrum of the oxidized species isolated
