通过X射线衍射分析阐明了四(五氟苯基)取代的N-稠合卟啉的抗磁性Cu(III)络合物的方形平面结构。 Cu(II) (1) 和 Cu(III) (2) 配合物之间的轻松相互转化是通过化学氧化/还原实现的，并且通过与外围 NH 的氢键相互作用添加阴离子来控制 Cu(III)/Cu(II) 氧化还原电位。
The square-planar structure of a diamagnetic Cu(III) complex of tetrakis(pentafluorophenyl)-substituted N-confused porphyrin was elucidated by X-ray diffraction analysis. The facile interconversion between Cu(II) (1) and Cu(III) (2) complexes was achieved by chemical oxidation/reduction, and the Cu(III)/Cu(II) redox potential was controlled by adding anions through the hydrogen-bonding interaction to the peripheral NH.
