Bis{[phthalocyaninato(2-)]antimony(III)} tetradecaiodotetraantimonate(III)

G. J. Perpétuo and J. Janczak

Abstract: The structure of the title compound, [Sb(C₃₂H₁₆N₈)]₂[Sb₄I₁₄] or [SbPc]₂[Sb₄I₁₄], where Pc is the phthalocyaninate(2-) macrocycle, is built up from separate but interacting [SbPc]⁺ cations and [Sb₄I₁₄]^2- anions. The Sb atom of the [SbPc]⁺ ion is bonded to four isoindole N atoms of the macrocycle and lies 0.974 (1) Å out of the plane defined by these four N atoms. The anion consists of [SbI₃] and [SbI₄]^- units which, through an inversion centre, form an [Sb₄I₁₄]^2- anion. The anions interact with each other, forming {[Sb₄I₁₄]^2-}_n chains. The arrangement of oppositely charged ions, viz. [SbPc]⁺ and [Sb₄I₁₄]^2-, in the crystal structure is determined mainly by the ionic attractions between the [SbPc]⁺ and [Sb₄I₁₄]^2- units and by - interactions between the aromatic macrocycles.
