The kinetics of the reduction of cis-[CoCl2(en)2] � (en = ethylenediamine) by iron(II) in Me2SO have been studied at four temperatures. The rate law has the form d[CoIII]/dt = kK [COIII][FeII]/(1+K[FII]) The pseudo-first-order rate constants determined at high [Fell] have been resolved into k and K, and their independent temperature dependence has been studied. The results are totally consistent with an inner-sphere electron-transfer process in which the precursor complex contains a double bridge using both the cis-chloro ligands and in which the iron atom is octahedrally coordinated.
