X-ray structures of gold corroles, which are still rather uncommon, afford significant insights into intramolecular 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 beta-octobromo-meso-tris(para-pentafluorosulfanylphenylcorrole, reported herein, has revealed two Au...Br interactions (similar to 4.2 angstrom) 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.
