COPPER(II) AND NICKEL(II) OCTABROMO-TETRAKIS(PENTAFLUOROPHENYL) PORPHYRIN COMPLEXES

The copper and nickel complexes of o-5,10,15,20-tetrakis(pentafluoro-p henyl)porphyrin fluorophenyl)-21,22,23,24-tetraazapentacyclo[16.2. ,9, 11,13(24),14,16,18(21),19-dodeca-ene}copper(II) 0.5-dichloromethane so lvate and ,9,-11,13(24),14,16,18(21),19-dodecaene}nickel(II) 0.5-dichl oromethane solvate) form isostructural crystals. There is significant distortion from planarity of the porphyrin ring caused by the octabrom o substituents interacting with the meso-pentafluorophenyl groups and with each other, with departures of the Br atoms from the plane define d by the four N atoms of up to 2.36 angstrom. This tetrahedral distort ion of the molecule does not result in any significant changes in bond distances from those in non-halogenated tetraphenylporphyrin complexe s.
