Abstract

Two electronically unsaturated tetraruthenium clusters, Ru₄(CO)₉(μPPh₂)[μ₄-Ph₂PCC(Ph)CC(Ph)] (2) and Ru₄(CO)₁₀(μPPh₂)[μ₄-Ph₂PC(Ph)CCC(Ph)] (3), with spiked-triangular and open-chain structures have been synthesized via head-to-tail and head-to-head coupling of binuclear acetylides: cluster 2 contains a coordinatively unsaturated metal center and undergoes a fully reversible triple addition of carbon monoxide to afford Ru₄(CO)₁₁(μ-PPh₂)[μ₄-Ph₂PC(O)CC(Ph)CC(Ph)] (4).
