The rate of the self-exchange reaction of NiII cyclam2+/NiII cyclam3+ measured using 61Ni e.s.r. and a marcus cross correlation reaction
Abstract
The e.s.r. spectra of labelled [NiIII1,4,8,11-tetra-azacyclotetradecane]3+(61Ni, I=) complexes have been used to determine the first rates of electron exchange between NiII- and NiIII-tetra-azamacrocycle complexes; independent measurements based on the reaction of FeIII(tris-polypyridine) complexes provide a more accurate value for the self-exchange parameter.
