(1,2-Benzenedicarbonitrile-κN)diiodo(phthalocyaninato-κ⁴N)zirconium(IV)

A new zirconium phthalocyanine complex [ZrI₂(Pc){C₆H₄(CN)₂}] (Pc = C₃₂H₁₆N₈) was obtained in crystalline form by the reaction of zirconium with 1,2-dicyanobenzene (o-DCB) under a stream of iodine. The molecule is a reaction product of zirconium, iodine atoms and o-DCB molecules, four of which form the Pc macrocycle. The crystal structure of this compound consists of discrete molecules in which seven-coordinate Zr(IV) is surrounded by four N atoms of the phthalocyaninato ligand, two cis-iodide atoms and an N atom from one of the cyano groups of the fifth o-DCB molecule. A set of hydrogen-bonded interactions links the molecules in the crystal lattice.
