Abstract

Thermolysis of [Ru₃(CO)₁₂] 1 in octane with guaiazulene (7-isopropyl-1,4-dimethylazulene) gave [Ru₃(CO)₇(μ₃-η⁵:η ³:η³-C₁₅H₁₈)] 2 and [Ru₄(CO)₉(μ₃-η⁵:η ³:η³-C₁₅H₁₈)] 3. The products 2 and 3 have been characterised by spectroscopic techniques and by single-crystal X-ray diffraction. Comparison is made between the two structures of the cluster compounds. Proton NMR and crystal structural data indicate an increased degree of metal-hydrocarbon interaction in 3.
