%X A 1H and 14N n.m.r. study of the exchange reaction Ni(MeCN)62+ &#8596; MeCN in MeCN solvent is reported. From the rate law: R = 6k298[Ni(MeCN)62+] the values k298 = (3.6 &#177; 0.6 ) &#215; 103 and (2.0 &#177; 0.3) &#215; 103 s-1; &#916;H&#8225; = 59.6 &#177; 8.8 and 68.4 &#177; 2.0 kJ rnol-1; and &#916;S&#8225; = 23 &#177; 16.7Jmol-1 K-1 and 50 &#177; 8.0 J mol-1 K-1 are derived from 1H and 14N data respectively. The apparent discrepancies between the two kinetic data sets, and the modes of relaxation of the 1H and 14N nuclei, are discussed.
