Adsorption of molecular chlorine on Au(111) has been studied with a low-temperature (5 K) scanning tunneling microscope in combination with density functional theory calculations. The formation of AuCl2 quasi-molecules was detected at chlorine coverage exceeding 0.33 ML. The self-organization of the AuCl2 species into the ordered ``honeycomb'' structure was clearly demonstrated for coverages close to saturation.
