An ESR study showed that the reversible addition of AsEt/sub 3/ to some square planar (cyclooctadiene)-o-semiquinone Rh(I) complexes is accompanied by an intramolecular electron transfer with information of pentacoordinated Rh(II) catecholate complexes. The term ..delta.. E(z/sup 2/ ..-->.. ..pi..SQ*), which is the difference in energy between the highest completely occupied MO of the complex (d/sub z//sup 2//) and the MO of the unshared electron localized on the SQ ligand in the initial Rh(I) complexes, is a practical criterion determining the feasibility of intramolecular electron transfer upon the coordination of AsEt/sub 3/.
