biostudies-literatureUnknown68(Pt 12)Miranda MDMol-ecules of the title compound, C52H38N4O8, are located on an inversion center so that the asymmetric cell contains one half of the mol-ecule. The macrocycle exhibits a ruffled conformation with a maximum deviation of 0.16 Å for the 24 macrocycle atoms: the dihedral angle between adjacent five-membered rings is 5.13 (19)°. The benzene rings are rotated by 70.25 (19)° with respect to their adjacent protonated five-membered rings, and by 65.56 (19)° with respect to the unprotonated rings. The porphyrin conformation is supported by bifurcated N-H⋯(N,N) hydrogen bonds. The structure contained poorly resolved solvent mol-ecules in voids of volume 217 Å(3) per unit cell. The latter were treated using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. As the solvent could Acta crystallographica.
