Iodo(phthalocyaninato)vanadium(III)

A new vanadium phthalocyanine complex with the formula [VI(C₃₂H₁₆N₈)], or PcVI (Pc=C₃₂H₁₆N₈), has been obtained by the reaction of pure V powder with 1,2-dicyanobenzene under iodine vapour. The V atom is bonded to one apical iodide ligand and four N_isoindole atoms, and has a square pyramidal coordination geometry. The mean V-N_isoindole distance is 1.952 (3) Å. The V-I bond is 2.6279 (8) Å long and is tilted 1.7 (1)° to the normal of the plane formed by the four N_isoindole atoms. The phthalocyaninato ligand is saucer-shaped.
