Dichloro(di-2-pyridylamine)gold(III) chloride

P.-F. Shi and Q. Jiang

Abstract: A new gold(III) complex of di-2-pyridylamine (DPA), [AuCl₂(C₁₉H₉N₃)]Cl, has been synthesized and characterized by ESI-MS, ¹H NMR spectroscopy, elemental analysis and X-ray structural analysis. The compound possesses crystallographically imposed mirror symmetry. The DPA ligand coordinates to the gold(III) centre in a bidentate mode. The distance between the metal centre and the Cl^- anion is 3.037 (2) Å. The cations are linked into layers parallel to the bc plane through N-HCl and C-HCl hydrogen-bond interactions. The title complex is more cytotoxic than cisplatin against A-549 and HCT-116 tumour cell lines.
