Reactions between {Ru(PPh3)(2)Cp}(2)(mu-C-4) and C-2(CN)(4) result in addition of the cyanocarbon to one of the C=C triple bonds and formation of the allylic complex Ru{eta(3)-C(CN)(2)C[C=C{Ru(PPh3)(2)Cp}]C=C(CN)(2)} (PPh,)Cp (2). In solution, 2 is in equilibrium with its dimer 3, the X-ray crystal structure of which has been determined. In 3, a ten-membered macrocyclic ring is present, being formed by displacement of the coordinated double bond in one molecule of 2 by a CN group from a second molecule.
