We have found a type of surface structure for a (2[times]2) arrangement formed on Cu(111) by Li deposition at 300 K, using dynamical low-energy electron-diffraction analysis. Its unit cell contains two Li adatoms located on fcc and hcp hollow sites and one Li atom substituting for a Cu atom; the Li coverage of each component is 1/4, for a total of 3/4 ML. The Li adatoms form a honeycomb structure whose rings surround the substituting Li atoms.
