[Cu(m-X)CuL](ClO4)3譓eOH (X = OH, N3, Br, I; L = I (R = H)) and [Cu(m-X')2CuL] (ClO4)2譓eOH (X' = Cl, SCN) were prepared L was prepared from 2,6-dimethylpyridine with conversion to the dialdehyde followed by condensation with 1,3-propanediamine. Kinetic of the O2- reaction of the 6 complexes are reported as are those for superoxide dismutase and [Cu(m-X)CuL](ClO4)3 (L = I (R = Me)). The results of riboflavin illumination method showed that the rate constants ~107 mol-1譫m3譻-1. Among them the complex with bridging SCN has the highest rate constant and that with bridging N3 has the lowest value. The reactions of complexes with O2- were studied by ESR. The reversible catalysis mechanism takes place in the reaction of SCN bridged complex, and the reaction of N3- bridged complex has irreversible oxidation. mechanism. Inhibition of N3- in this complex is similar to that of N3 to superoxide dismutase.
