| Abstract: | We have obtained complexes of Co(II) with 1,4-piperazine-bis(carbothiosulfene diethylamide) (L) of composition Co2LX4] (X = Cl, Br, I, NCS). We discuss the characteristic features of the decomposition kinetics for H2O2 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
α and β in the Edwards equation to a considerable extent are due to the composition of the complexes and the ratio H2O2]0/Cat]0. |
