Ru, Rh, and Ir trinuclear mixed-valence oxygen-bridged carboxylate complexes

A model is suggested that can be used to explain the structure of amorphous (glassy) mixed-valence Z trinuclear mu(3)-oxocarboxylate complexes of ruthenium, rhodium, and iridium. In the framework of this model, individual metal-containing blocks that formally occur in different oxidized states are considered to be structurally and functionally integrated in a single supramolecular construction.
