Abstract
The vanadyl complex oxo[5,10,15,20-tetrakis(pentafluorophenyl)porphyrinato- kappa(4)N] vanadium(Iv) dichloromethane solvate, [VO(C44H8F20N4)]. CH2Cl2, crystallizes in the monoclinic space group P2(1)/c, with four molecules per unit cell. The V atom is found to lie 0.5237(5)Angstrom above the mean pla ne of the porphyrin core. The average V-N distance is 2.067(5)Angstrom and the V=O bond length is 1.585(2)Angstrom. The doming of the porphyrin core i s characteristic of five-coordinate metalloporphyrins. Moreover, the macroc ycle is slightly saddle-shaped and ruffled. Van der Waals contacts between the phenyl rings and the solvent molecules lead to dihedral angles between these phenyl rings and the porphyrin core mean plane ranging from 58.23(5) to 89.38(6)degrees. These contacts could explain the deviation of the porph yrin geometry relative to the fourfold symmetry.
