A new synthetic route for the preparation of [Os3(CO)10(μ-OH)(μ-H)] and its reaction with bis(diphenylphosphino)methane (dppm): syntheses and X-ray structures of two isomers of [Os3(CO)8(μ-OH)(μ-H)(μ-dppm)] and [Os3(CO)7(μ3-CO)(μ3-O)(μ-dppm)] (open access)

A new synthetic route for the preparation of [Os3(CO)10(μ-OH)(μ-H)] and its reaction with bis(diphenylphosphino)methane (dppm): syntheses and X-ray structures of two isomers of [Os3(CO)8(μ-OH)(μ-H)(μ-dppm)] and [Os3(CO)7(μ3-CO)(μ3-O)(μ-dppm)]

Article describes a convenient synthetic method for the preparation of the hydroxy-bridged triosmium cluster [Os₃(CO)₁₀(μ-OH)(μ-H)] along with the re-evaluation of the reaction of this cluster with dppm that has led to the isolation of a new isomer for [Os₃(CO)₈(μ-OH)(μ-H)(μ-dppm)].
