[Phthalocyaninato(2-)]arsenic(III) triiodide

J. Janczak and Y. M. Idemori

Abstract: A new arsenic(III) phthalocyanine complex with the formula [As(C₃₂H₁₆N₈)]I₃, or AsPcI₃ (Pc = C₃₂H₁₆N₈), has been obtained by the reaction of pure powdered arsenic with phthalonitrile under a stream of iodine vapor. The four-coordinate As atom is bonded to the four isoindole N atoms of the phthalocyaninate(2-) macro-ring and lies significantly out of the plane defined by the four isoindole N atoms [0.757  (2)  Å]. The I atoms form linear asymmetric triiodide I₃^- ions. In the crystal, the I₃^- ions related by an inversion center form (I-I-II-I-I)^2- ions.
