N2  - Tris picolinate complexes of CO111 and RU111 have been synthesized, and their standard potentials measured (432 ±10, 403 ±2 mV) at 25ºC and ionic strength 0.1 mol dm-3. The self-exchange rate constant of Ru ( pic )3O/- was found to be (1 .4 ±0.9)&#215;108 dm3 mol-1 s-l, from reaction with cytochrome C(II), Co( bpy )32+ and ~Co( phen )32+. For the reaction between Fe( dipic )2- and cytochrome ~(II), at 2S260C, pH 5.5 and I 0.1 mol dm-3 (KNO3), the second-order rate constant was (3.2 ±0.l)&#215;105 dm3 mol-1 s-1,with &#916;H+ 19.9 ±0.9 kJ mol-1 and &#916;S+ -72.8 ±.7 J K-1 mol-l. The self-exchange rate constant of Fe( dipic )2-/2- was reevaluated as (5.8 ±0.2)&#215;106 dm3 mol-l s-1.
