Abstract

The reactions between Ru₂(ap)₄Cl and the appropriate lithiated aryl acetylene resulted in the complexes (4), 1,3-[Ru₂(ap)₄(C≡C)₂] C₆H₃-5-C≡CH (5) and 1-[Ru₂(ap)₄(C≡C)]C₆H₃ -3,5-(C≡CH)₂ (6), where ap is 2-anilinopyridinate. The spectroscopic and electrochemical properties of the new complexes have been assessed. Complexes 3, 4 and 6 display two-electron oxidation and reductions, implying the absence of any significant electronic interaction between the two Ru₂(ap)₄ units in these complexes.
