Atomic structures formed on the Ag(111) surface as a result of molecular chlorine adsorption have been studied with a low-temperature scanning tunneling microscopy (LT-STM) in a combination with DFT calculations. We have found that saturated chlorine coverage on Ag(111) is a complex system consisting of two different structural phases: small anti-phase domains of a (3 x 3) reconstruction and nanoclusters Ag3Cl7.
