There have been numerous publications concerning electron transfer processes with the participation of macrobicyclic complexes. Moreover, cobalt(II) and cobalt(III) complexes have received the most attention, presumably due to their availability. Several papers deal with electrochemistry of chromium, ruthenium, rhodium, manganese, nickel, iron, and copper complexes. 

The electrochemistry of metalloporphyrins with o-bonded alkyl or aryl groups has been reported for complexes with nine different central metals. These include transition metal complexes of cobalt rhodium , and iridium , and... 

Cobalt, Rhodium and Iridium The pentaphenylcyclopentadienyl ligand has been the subject of three different reports, all based on complexes of the form (C5Ph5)M(CO)2 (M=Co or Rh) made for example by the reaction of Na(CsPh5) with [RhCl2 (CO) 2 ] 2 structure and electrochemistry have... 

The Ru(II)-Rh(III) cyanide-bridged complexes show absorptions that are characteristic for ruthenium and rhodium polyazine complexes. The electronic absorption spectra of a series of cyanide-bridged Ru(H)-Rh(ni) complexes recorded in DMSO-H2O solutions correlate well with the electrochemical properties. Coordination of a second Rh(III) shifts the lowest energy transition, which is Ru bpy MLCT in nature, to higher energy in [(bpy)2Ru (CN)Rh(NH3)5 2] relative to [(bpy)2(CN)Ru(CN)Rh(NH3)5] . This positive shift is consistent with the stabilization of the Ru(djt) orbitals of [(bpy)2Ru (CN)Rh(NH3)5 2] and correlates well with the electrochemistry where the Ru° oxidation moves to more positive potential with Rhflll) addition. The of... 

Numerous reports of o-bonded cobalt, rhodium and iridium porphyrins have appeared in the literature but the electrochemistry of these complexes is limited to only several preliminary studies. Three laboratories have reported the electrochemistry of (TPP)Co(R) ,22, Two laboratories have reported the electrochemistry of (OEP)Ir(R) , and (OEP)Ir(R)(L)2 and only a single laboratory has reported the electrochemistry of (TPP)Rh(R)2 - o.
