Reductions of Co(edta)-, Co(NH3)63+, Co(en)33+, and Co(sep)3+ by tris(picolinato)vanadate(II), V(pic)3-, take place with second-order rate constants 7.7 × 104 M-1 s-1, 8.0 × 103 M-1 s-1, 8.2 × 102 M-1 s-1, and 8.4 × 104 M-1 s-1, respectively, at 25.0°C and at 0.5 M ionic strength. Application of the Marcus theory to the latter three results leads to a self-exchange rate for V(pic)30/- of 3.1 × 106 M-1 s-1. For Co(edta)- the observed rate is an order of magnitude slower than predicted by the Marcus theory and reasons for this discrepancy are proposed.
