Crystal structures of 2,3,7,8,12,13,17,18-octa­bromo-5,10,15,20-tetra­kis­(penta­fluoro­phen­yl)porphyrin as the chloro­form monosolvate and tetra­hydro­furan monosolvate

The crystal structures of the title compounds, two solvates (CHCl(3) and THF) of a symmetric and highly substituted porphyrin, C(44)H(2)Br(8)F(20)N(4) or OBrTPFPP, are described. These structures each feature a non-planar porphyrin ring, exhibiting a similar conformation of the strained ring indepen...

Sumario:The crystal structures of the title compounds, two solvates (CHCl(3) and THF) of a symmetric and highly substituted porphyrin, C(44)H(2)Br(8)F(20)N(4) or OBrTPFPP, are described. These structures each feature a non-planar porphyrin ring, exhibiting a similar conformation of the strained ring independent of solvent identity. These distorted porphyrins are able to form hydrogen bonds and sub-van der Waals halogen inter­actions with enclathrated solvent; supra­molecular inter­actions of proximal macrocycles are additionally affected by solvent choice. The crystal studied for compound 1·CHCl(3) was refined as an inversion twin. One penta­fluoro­phenyl group was modelled as disordered over two sites [occupancy ratio = 0.462 (7):0.538 (7)]. The chloro­form solvate was also modelled as disordered over two orientations [occupancy ratio = 0.882 (7): 0.118 (7).
