Abstract

Reactions between RuCl(PPh3)2(η-C5H5) and AgC2Ph afforded a deep blue binuclear complex, shown by X-ray crystallography to contain a planar tricyclic diruthenadicyclobutadien[a, c]benzene system, formed by tetramerisation of phenylacetylide residues at the ruthenium centres. A deep purple complex, isolated in small yield from the same reaction, was similarly shown to contain a diruthenapentacyclic system, formed by an unprecedented oligomerisation of five phenylacetylide units. Related reactions have given [{Ru(C2Ph)(PPh32(η-C5H5)}2Ag][PF6] and the divinylidene [{Ru(PPh3)2(η-C5H5)}2(μ-C4Ph2)][PF6]2.
