Popis:	Reaction of Ru3(CO)12 and S(CCSiMe3)2 in toluene gave [Ru3(CO)9(μ-η2-SCCSiMe3)(μ3-η2-CCSiMe3)] 1. The thermolysis of 1 provokes the rupture of the S–Csp bond of the SCCSiMe3 ligand and C–C coupling reactions between two acetylide groups affording the clusters [Ru3(CO)9(μ3-S)(μ3-η2-C(SiMe3)C(CCSiMe3)] 2, [Ru2(CO)6(μ-η3-SCCSiMe3)(μ-η2-CCSiMe3)] 3, [Ru4(CO)12(μ4-S)(μ-η2-CCSiMe3)2] 4 and [Ru4(CO)9(μ-CO)2(μ4-S)(μ4-η2-C(SiMe3)C(CCSiMe3)] 5. All compounds have been characterized by IR and NMR techniques as well as FAB+ mass spectrometry. Crystal structures of 1, 4, and 5 have been determined by X-ray diffraction methods. The pathways of the thermolysis of 1 to give 2–5 have been investigated.
