Kinetics of hydrogen peroxide decomposition in the presence of binuclear complexes of cobalt(II) with 1,4-piperazine-bis(carbothiosulfene diethylamide)
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...

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 [H
