The synthesis and characterisation of nickel(III) complexes are reviewed. Kinetic aspects of redox reactions including oxidation by Co(OH 2 ) 3+ 6 and Fe(phen) 3+ 3 are described, as are the reactions involving oxidation of non‐metallic substrates. Reference is made to the evaluation of self‐exchange rates for the Ni(III)L/Ni(II)L couples, especially for systems where both oxidant and reductant retain an octahedral geometry. Using the reversible reaction between Ni(9‐aneN 3 ) 3+ 2 and Ni(10‐aneN 3 ) 3+ 2 (9‐ane = 1,3,7‐triazanonane, 10‐ane = 1,3,7‐triazadecane), data are presented for evaluation of the self‐exchange rate constant for the Ni(10‐aneN 3 ) 3+/2+ 2 couple [(7.5 ± 1) X 10 3 M −1 s −1 ]. This value is compared with that for similar systems where changes in bond lengths on oxidation have been determined by X‐ray techniques.
