Abstract: The reaction of [Ru3(CO)12 ] with dimer of p-methoxyphenyl thionophosphine sulfide in THFyields the novel trinuclear ruthenium carbonyl cluster [( μ-H)] 2Ru3(CO)9( μ3-P)](Ⅰ) and tetranuclear ruthenium carbonyl cluster (Ⅰ) and tetranuclear ruthenium carbonyl cluster [Ru4(CO)10 ( μ3-PC6H4OMe)](Ⅱ). These clusters were characterized by elemental analysis, IR, 1H NMR, 31P NMRand MSspectrometric methods and the molecular structure of compound Ⅰ was determined by X-ray diffraction analysis. The molecular geometry of compound Ⅰ contains a trigonal pyramid Ru3Pskeleton with a Ru3 triangle at the base and the nude phosphorus atom as a 5e μ3-Pbridging ligand at the apex. Though compound Ⅰ is one with 49 valence eletron, its Ru-Ru distances(average 0.2830 nm) are astonishly short and compound Ⅰ is rather stable in the exposure to oxygen and moisture. The structure of compound Ⅱ is believed to have a tetrahedral Ru4 core which is attached to a μ3 Sand a μ3-PC6H4OMe ligand on tetrahedron's two triangular faces.

Key words: Ruthenium carbonyl cluster, Nude phosphorus atom, Phosphorus and sulfur ligands
