%X Kinetic studies of the decomposition reaction of dinuclear Fe(II) adducts Fe2(N-Et-HPTB)O2P(OPh)2}(Cl-O4) 2 (1) and Fe2(N-Et-HPTB) {O2P(Ph)2}] (ClO4)2 (2) with O2 have been carried out at low temperature using UV-vis spectra. The decomposition reaction of Fe(II)/O2 adducts was first-order in the experimental conditions, and the activation parameters were obtained. ΔH≠ = 85.62 kJ · mol 1, ΔS≠ = 19.43 J · mol 1 · K 1 for compound (1) and ΔH≠ = 97.97 kJ · mol 1, ΔS≠ = 55.68 J · mol 1 · K 1 for compound (2). These results are similar to those of dioxygen adducts of other metals complexes and natural enzymes such as methane monooxygenase (MMOH).
