Abstract
The rates at which 2,2′,2″-terpyridine reacts with nickel(II) ion to form the monoligand–nickel(II) and the bisligand–nickel(II) complexes were determined in DMSO solution. Ni(terpy)Cl 2 was isolated, and used to study the rate of formation of bis complex. The second-order rate constants were found to parallel the rates of DMSO exchange, determined using n.m.r. techniques, from the respective paramagnetic nickel species. Attempts were made to relate the results to the generally accepted "dissociative" pathways for this class of substitution reactions.
