- 6Collman et al. have also reported the dioxygen reaction with different types of iron(II)- or cobalt(II)-porphyrin-linked copper(I) dinuclear complexes and the formation of the corresponding peroxo species: , Inorg. Chem. 1997, 36, 5145, and references therein.
- 7The peroxo complex 2 in CH3CN solution is stable for several days at room temperature. It gradually decomposes, to give the mixture of corresponding μ-oxo and μ-hydroxo complexes, as reported in ref. [4] and [5]. Detailed studies of the decomposition mechanism are in progress.
- 8The X-ray experiments for complexes 2 were carried out on a Rigaku RAXIS imaging plate area detector with graphite monochromated CuKα radiation (λ=1.54178 Å). The crystal was mounted on a glass fiber. The data were collected (3.5≤2θ≤136.5°) at −150 °C. To determine the cell constant and orientation matrix, three oscillation photographs were taken with an oscillation angle of 5.0° and exposure time of 60 s per degree for each frame. Intensity data were collected by taking 180 oscillation photographs with an oscillation angle of 5.0° and exposure time of 90 s per degree for each frame. Refraction data were corrected for both Lorentz and polarization effects. 2: C98H87N9O3Cu1Fe1B1, dark purple crystals, monoclinic, P21/n, a=14.2898(4), b=13.0041(3), c=50.368(1) Å, β=91.4898(7)°, V=9356.6(4) Å3, Z=4, ρcalcd=1.114 g cm−3, 91 575 reflections collected, 15 999 reflections used and 1126 parameters.
