The title compound shows significant conformational distortion in the vicinity of the ![[beta]](/logos/entities/beta_rmgif.gif)
-nitro group. This is attributed to steric interaction between a meso-phenyl and the -nitro group. The overall degree of conformation distortion is moderate, the average deviation of the 24 macrocycle atoms from their least-squares plane being 0.08 Å. The largest displacements (0.33 Å from the plane of the four pyrrole nitrogen atoms) were found for the Cb-positions of the nitrated pyrrole ring.
