Abstract

Title full: Ruthenium carbonyl cluster complexes with nitrogen ligands. II. Syntheses, X-ray structures and interconversion of Ru₃(μ-H)(μ-η²-NC₅H₈)(CO)₁₀ and RU₃(μ-H)(μ₃-η²-NC₅ H₈)(CO)₉. The reaction between piperidine and Ru₃(CO)₁₂ in refluxing tetrahydrofuran gave the title compounds Ru₃(μ-H)(μ-η²-NC₅H₈)(CO)₁₀ (1) and Ru₃(μ-H)(μ₃-η²-NC₅ H₈)(CO)₉ (2), both of which have been characterized by means of X-ray diffraction studies, with location and refinement of the core hydrogen atoms. Analysis of the cluster core distances for 1, 2 and related structures suggests that there is substantially more NC weakening for μ₃-η²- compared to μ-η²-coordination. Interconvertibility of 1 and 2 has been demonstrated. Mild thermolysis cleanly converted 1 into 2; the reverse reaction could be quantitatively effected by carbonylation at room temperature. Hydrogenation of 2 effected the elimination of the μ₃-η²-piperidyl ligand.
