Vanadyl Tetrakis(pentafluorophenyl)porphyrin Dichloromethane Solvate

The vanadyl complex oxo[5,10,15,20-tetrakis(pentafluorophenyl)porphyrinato-κ⁴N]vanadium(IV) dichloromethane solvate, [VO(C₄₄H₈F₂₀N₄)].CH₂Cl₂, crystallizes in the monoclinic space group P2₁/c, with four molecules per unit cell. The V atom is found to lie 0.5237 (5) Å above the mean plane of the porphyrin core. The average V—N distance is 2.067 (5) Å and the V=O bond length is 1.585 (2) Å. The doming of the porphyrin core is characteristic of five-coordinate metalloporphyrins. Moreover, the macrocycle is slightly saddle-shaped and ruffled. van der Waals contacts between the phenyl rings and the solvate molecules lead to dihedral angles between these phenyl rings and the porphyrin core mean plane ranging from 58.23 (5) to 89.38 (6)°. These contacts could explain the deviation of the porphyrin geometry relative to the fourfold symmetry.
