Abstract
The temperature-jump relaxation method has been used to measure rate constants for the formation (k(f)) and dissociation of ternary complexes between 2,2'-bipyridine (bipy), 4,4'-dimethyl-2,2'-bipyridine and 5-nitrosalicylate (2-) (nsa(2-)), respectively, and [Zn(nta)(H2O)](-) [nta = nitrilotriacetate(3-)]; also for proton transfer between Hnsa(-)/nsa(2-) and various buffers. The effects of pH and buffer on the ternary complexation kinetics have been investigated, and independent equilibrium constants are reported for the formalin of several [Zn(nta)B] (B = buffer) complexes. Values of k(f) for bipy and nsa(2-) are similar to those for the corresponding reactions of cobalt(II).
