Thermal Solid/Gas Reactions of the Triruthenium Cluster [Ru₃(μ₃-O)(μ₂-CH₃COO)₆(CO)(L)₂]

Abstract

The elimination and substitution reactions of the terminal ligands L(H₂O, CH₃OH and pyridine) of the triruthenium cluster in the solid state were studied mainly by thermogravimetric analysis in nitrogen gas, vacuum, methanol vapor and pyridine vapor with various heating rates. The reaction schemes for the solid/gas reactions were presented. It was suggested that one or two vacant sites in the terminal positions can be formed during the elimination of the terminal methanol or water, which may be an active site for solid/gas rections.
