More noble than ever : The first fully inorganic discrete polynuclear gold(III) oxo complex [Au III 4 As V 4 O 20 ] 8− (see structure; Au yellow, As blue, O red) was prepared by condensation of [Au(OH) 4 ] − in the presence of AsO 4 3− ions under mild reaction conditions. The resulting polyoxoaurate exhibits a tetrameric structure with square‐planar coordinated Au III ions linked by oxo and arsenate bridging ligands.
