Bonds and backbonding

There have been two books that contain compilations of the electrochemistry of Os (572,573). There have also been reviews that cover the electrochemistry of certain classes of complexes with ligands such as porphyrins (142), dithiocarbamates (463), and macrocyclic complexes (39, 93). The purpose of this section is not to provide a comprehensive review of electrochemical studies over recent years, but rather to give some insight into the factors that affect the redox potentials and their use in obtaining information about 7r bonding and backbonding. Particular emphasis is placed on the similarities and differences between analogous Os and Ru complexes.
