Molecular structure of gold 2,3,7,8,12,13,17,18-octabromo-5,10,15-tris(4′-pentafluorosulfanylphenyl)corrole: Potential insights into the insolubility of gold octabromocorroles

X-ray structures of gold corroles, which are still rather uncommon, afford significant insights into intermolecular interactions involving Au(III), a subject that has been much less studied than aurophilic and metallophilic interactions involving Au(I). The X-ray structure of gold β-octabromo-meso-tris(para-pentafluorosulfanylphenyl)corrole, reported herein, has revealed two Au···Br interactions (∼4.2 A) per Au atom. We suggest that analogous but somewhat stronger Au···Br interactions are a key factor underlying the remarkable insolubility of gold octabromocorrole derivatives.
