Thermal stability of mixed-valent diruthenium (II,III) carboxylates

The thermal stability of mixed-valent diruthenium carboxylates, Ru2 II,III (O2CR)4X, where RCO2 - are the equatorial carboxylates and X- is the axial ligand (halide or carboxylate anion) was investigated. The nature of the axial ligands determines two decomposition pathways, while the equatorial car...
