## Abstract We have examined the electronic and geometrical effects of the progressive addition of bulky electron‐withdrawing NO~2~ groups at the adjacent __meso__ positions of Fe^III^‐μ‐oxo octaethylporphyrin dimers. The successive addition of mono‐, di‐, tri‐, and tetranitro substituents at the _
