Abstract	The reaction of Pt$_{2}$Ru$_{4}$(CO)$_{18}$, 1 with 1,8-bis(phenylethynyl)naphthalene, 2 has yielded two metal carbonyl cluster complexes: Ru$_{2}$(CO)$_{6}$[μ-η $^{2}$-C$_{10}$H$_{6}$C$_{4}$Ph$_{2}$], 3 (60% yield) and Ru$_{2}$Pt(CO)$_{6}$[μ-η $^{2}$-C$_{10}$H$_{6}$C$_{4}$Ph$_{2}$]$_{2}$, 4 (8% yield). Both compounds were characterized by a single crystal X-ray diffraction analysis. Both products were formed as a result of fragmentation of the Pt$_{2}$Ru$_{4}$ cluster of 1. Compound 3 contains two ruthenium atoms. They are bridged by a tricyclic C$_{10}$H$_{6}$C$_{4}$Ph$_{2}$ ligand formed by the coupling of the two α-carbon atoms of the alkyne groups. The β-carbon atoms of the alkynes are σ-bonded to one of the ruthenium atoms to form a metallacycle and this entire group is π-bonded to the second ruthenium atom. Compound 4 contains two ruthenium atoms with a platinum atom between them. This molecule contains two tricyclic C$_{10}$H$_{6}$C$_{4}$Ph$_{2}$ ligands similar to that in 3, and two metallacycles formed by coordination of the β-carbon atoms of both ligands to the platinum atom. One ligand is π-bonded to each of the ruthenium atoms.
