%X A single acetonitrile exchange process on Co(diap)(MeCN)32+ (where diap is 2,2-di(aminomethyl)-propan-1-ol) in acetonitrile solution is observed by 14N N.M.R. between 221 and 315.6 K. On the assumption that this process characterizes the two equivalent acetonitrile sites the following parameters are derived: kex(298 K) = (45 ± 3) x 105 s-1, &#916;H? = 3l.0 ± 2.5 kJ mol-1, &#916;S? = -l4 ± 6 J Mol-1 K-1, where the exchange rate is given by 2kex[Co(diap)(MeCN)32+]. Alternative interpretations are also discussed.
