dc.description.abstract	The electron-deficient compound [(µ-H)Os₃(CO)₈-{Ph₂PCH₂P(Ph)C₆H₄}] 2 reacts with 2-mercaptoimidozole, 2- mercaptobenzimidazole and 2-mercaptobenzothiazole at 80°C to give [(µ-H)Os₃(CO)₈(µ-dppm)(µ-η¹-SN₂C₃H₃)] 3, [(µ-H)Os₃(CO)₈(µ-dppm)(µ-η¹-SN₂C₇H₅)] 4 and [(µ-H)Os₃(CO)₈(µ-dppm)(µ-η¹-SN₂C₇H₅)] 5 in 30, 50 and 59% yields, respectively. The compounds are formed by the oxidative addition of S-H bond followed by demetallation of the phenyl ring of the orthometallated dppm ligand. Compounds 3-5 have also been obtained from the reactions of [Os₃(CO)₁₀(µ-dppm)] 1 with 2- mercaptoimidozole, 2-mercaptobenzimidazole and 2- mercaptobenzothiazole, respectively at 110ºC but in some what lower yields. The compounds have been characterized by elemental analysis, IR, ^IH NMR and ³¹p{¹H} NMR spectroscopic data together with single crystal X-ray diffraction studies for 3. Compound 3 crystallizes in the triclinic space group PI with a=11.3453(12), b=13.651(2), c=15.069(2) Å, α=84.709(l1), b=72.7C6(9), γ=68.265(9)º, Z=2 and V=2069.5(4) Å³. The structure consists of an equilateral triangle of osmium atoms with a bridging dppm, a bridging hydride and a bridging 2- mercaptoimidazolato ligand.	en_US
