Molecular Gold Wire from Mixed‐Valent AuI/III Complexes

Crystals of mixed‐valent Au complexes have been grown from solutions of cyclohexanecarbonitrile and a stoichiometric amount of gold(I) and gold(III) chloride. The purely obtained compound was characterized as bis(cyclohexanecarbonitrile)gold(I) tetrachloridoaurate(III). The crystal packing of the mixed valent Au(I/III) compound demonstrates a columnar arrangement of the gold(I) and gold(III) atoms. The new structure displays the shortest unsupported gold(I)–gold(III) interactions with the sub‐van der Waals distance of 324–325 pm, which is assumed as an aurophilic bonding interaction.
