Ring-strain release in neutral and dicationic 7,8,17,18-tetra­bromo-5,10,15,20-tetra­phenyl­porphyrin: crystal structures of C(44)H(26)Br(4)N(4) and C(44)H(28)Br(4)N(4) (2+)·2ClO(4) (−)·3CH(2)Cl(2)

Two porphyrin complexes were studied to determine the effects of protonation on ring deformation within the porphyrin. The porphyrin 7,8,17,18-tetra­bromo-5,10,15,20-tetra­phenyl­porphyrin, C(44)H(26)Br(4)N(4), was selected because the neutral species is readily doubly protonated to yield a dication...
