The reaction of dodecacarbonyltriruthenium with 1,3,5‐trithiacyclohexane (1,3,5‐trithiane) in refluxing THF yields [Ru 3 (CO) 6 (μ 2 ‐CO) 3 {μ 3 ‐(η 3 ‐C 3 S 3 H 6 )}] ( 1 ) in which the three S‐atoms of the cyclic ligand coordinate to the three Ru‐atoms of the metal core. X‐Ray diffraction reveals a nearly perfect C 3v symmetry for the molecule. The variable‐temperature 13 C‐NMR spectra show the carbonyl ligands to be fluxional in solution.
