Abstract

The reaction of Ru₃(CO)₁₂ with Pt(IMes)₂ in benzene solvent at room temperature afforded the monoplatinum-triruthenium cluster complex Ru₃Pt(IMes)₂(CO)₁₁, 1, in 21% yield and the trigonal bipyramidal cluster complex Ru₃Pt ₂(IMes)₂(CO)₁₂, 2, in 26% yield. The reaction of Ru(CO)₅ with Pt(IMes)₂ in benzene solvent at 0 C yielded two trinuclear cluster complexes, the monoplatinum-diruthenium Ru ₂Pt(IMes)(CO)₉, 3, and the monoruthenium-diplatinum cluster complex RuPt₂(IMes)₂(CO)₆, 4. The reaction of 2 with hydrogen at 80 C afforded the tetrahydrido-tetraruthenium complex Ru₄(IMes)(CO)₁₁(μ-H)₄, 5, and the dihydrido-diruthenium-diplatinum complex Ru₂Pt₂(IMes) ₂(CO)₈(μ-H)₂, 6. All six compounds were structurally characterized by single-crystal X-ray diffraction analyses.
