Abstract

Reaction of the heteronuclear cluster RuOs₃(μ-H) ₂(CO)₁₃ (1) with azulene under thermal activation afforded the novel clusters RuOs₃(μ-H)(CO)₉(μ₃, η⁵:η²:η²-C₁₀H ₉) (3) and Ru₂Os₃(μ-H)₂(CO) ₁₃(μ-CO)(μ₃,η⁵:σ²- C₁₀H₈) (5a), with 4,6,8-trimethylazulene to give RuOs ₃(μ-H)(CO)₈(μ-CO)(μ,η⁵: η⁴-C₁₀H₆Me₃) (4) and Ru ₂Os₃(μ-H)₂(CO)₁₃(μ-CO) (μ₃,η⁵:σ²-C₁₀H ₅Me₃) (5b), and with guaiazulene to give Ru ₂Os₃(CO)₁₁(μ₃,η⁵: η³:η³-C₁₀H₅Me ₂ⁱPr) (6), respectively. In 3-5, cluster-to-ligand hydrogen transfer appears to have taken place, with the organic moiety capping a trimetallic face in 3, bridging a metal-metal bond in 4 and via a μ₃,η⁵:σ² bonding mode in 5a and 5b. Cluster 6 contains a trigonal bipyramidal metal framework with the guaiazulene ligand over a triangular metal face. All five clusters have been completely characterised, including by single-crystal X-ray diffraction analysis.
