5-[4-(Dieth­oxy­phosphor­yl)-2,3,5,6-tetra­fluoro­phen­yl]-10,15,20-tris(penta­fluoro­phen­yl)porphyrin

The title compound, C₄₈H₂₀F₁₉N₄O₃P, prepared by the nucleo­philic attack of triethyl phosphite on one of the 4-fluoro atoms of 5,10,15,20-tetra­kis­(penta­fluoro­phenyl)por­phy­rin, contains a single mol­ecule in the asymmetric unit. The porphyrin unit is almost planar [largest non-H atom deviation = 0.174 (6) Å], and has the planes of the neighbouring benzene rings oriented at angles ranging from 64.3 (2) to 89.6 (3)° relative to the porphyrin core. The P=O group is almost coplanar with the attached benzene ring, subtending an angle of 4.0 (3)°. Several weak supra­molecular inter­actions, namely C—H...π, C—F...π, P=O...π, C—H...(O,F) and F...F contacts, contribute to the crystal packing.
