title: mu4-Dicarbyne complex with a dimetallacyclobutatriene core: a new binding mode of C2 species.
abstract: Reaction of a permetallated ethene, (mu4-C=C)Fe2R-mu2Cp*2(CO)10, with diphenylacetylene affords the adduct with a new C2-binding mode, a mu4-dicarbyne complex, (mu4-C-C)Fe2Ru2Cp*2(CO)6(mu-Ph-C[triple bond]C-Ph), containing a dimetallacyclobutariene core.
