Rate constants and activation parameters for the formation and the dissociation of the monocomplex of nickel(II) with thiocyanate ion in dimethylsulfoxide have been determined by stopped-flow measurements. The results for thiocyanate ion, and also those for several other unidentate ligands, are consistent with a dissociative interchange mechanism in which solvent exchange constitutes the rate-determining step. On the other hand, previous results have shown that for multidentate ligands the ring-closure step also may be rate limiting.
