Abstract

The clusters [Os₃(CO)₁₁ (MeCN)] and [Os₃(CO)₁₀(MeCN)₂] react with acids HX (X = BF₄ or PF₆) to form the cationic derivatives [Os₃(μ-H)(CO)₁₁(MeCN)]X and [Os₃(μ-H)(CO)₁₀(MeCN)₂]X, respectively. The cluster [Os₃(CO)₁₀(MeCN)₂] also reacts with dry HCl to form the salt [Os₃(μ-H)-(CO)₁₀(MeCN)₂][Os(CO) ₃Cl₃]. X-Ray analysis of this salt shows that the Os atoms in the cation lie at the vertices of an isosceles triangle. A hydride bridges the long Os-Os edge, and the two acetonitrile ligands occupy trans axial sites. Reaction of [Os₃(μ-H)(μ-OH)(CO)₁₀] with HBF₄ in MeCN also produces [Os₃(μ-H)(CO)₁₀(MeCN)₂]⁺. In this reaction direct attack of H⁺ on the co-ordinated OH^- ligand is considered to occur with the resultant liberation of H₂O. Treatment of [Os₃(μ-H)(CO)_10-(MeCN)₂] ⁺ with [Os(CO)₄]^-2 leads to the formation of the neutral complex [Os₄H₂(CO)₁₄(MeCN)]. The bridging hydride of the cation may also be replaced by a bridging nitrosyl ligand by reaction with NO⁺.
