摘要：

We have obtained complexes of Co(II) with 1,4-piperazine-bis(carbothiosulfene diethylamide) (L) of composition [Co(2)LX(4)] (X = Cl, Br, I, NCS). We discuss the characteristic features of the decomposition kinetics for H(2)O(2) in the presence of these complexes and the effect of the acido ligands X on their catalytic activity. We have observed isokinetic relationships between the activation parameters and the reaction rate constants. We show that the values of the parameters alpha and beta in the Edwards equation to a considerable extent are due to the composition of the complexes and the ratio [H(2)O(2)](0)/[Cat](0).
