Abstract

<span style="mso-bidi-font-size:12.0pt;mso-fareast-font-family:SimSun" lang="EN-GB">Treatment of <span style="mso-bidi-font-size:12.0pt" lang="EN-GB">electron-deficient Os₃(CO)₈{μ₃-Ph₂PCH(CH₃)-P(Ph)C₆H₄}(μ-H) (<b>1</b>) with HCl at room temperature furnishes the adduct Os₃(CO)₈{μ-Ph₂PCH(CH₃)PPh₂}(μ-Cl)(μ-H) (<b>2</b>) in almost quantitative yield via oxidative addition of H‒Cl bond. Cluster (<b>2</b>) is electron-precise and contains bridging chloride and hydride ligands which rearranges upon heating at 110 °C to form isomeric (<b>3</b>). Both clusters have been characterized by a combination of elemental analyses, IR and NMR spectroscopic data together with single crystal X-ray diffraction studies.<span style="mso-bidi-font-size:12.0pt;mso-fareast-font-family:SimSun" lang="EN-GB">
