  "abstract": "We have reanalyzed the 0.25 and 0.50 monolayer (ML) phases of oxygen on the catalytically important Rh(100) surface by quantitative low-energy electron diffraction (LEED), variable-temperature scanning tunneling microscopy (STM) and density functional theory (DFT). For both phases, the crystallographic structure could be determined by LEED structure analyses with single-digit picometer precision enabled by ultra-low Pendry R factors of R$_\\mathrm{P}$ $\\approx$ 0.07. For the (2$\\times$2)-O phase at 0.25 ML we find oxygen adsorbed at fourfold hollow sites in accordance to earlier results [Surf. Sci. 207 (1988) 55], however, with a pronounced buckling within the second layer of the otherwise unreconstructed substrate. For the 0.50 monolayer phase, we recently identified a (2$\\sqrt{2}$ $\\times$ 2$\\sqrt{2}$)R45$^\\circ$-4O ground state structure [Phys. Rev. Res. 8 (2026) 023296], which decomposes into a large number of nano-domains already at temperatures below 100 K. In this paper we provide a detailed analysis of the atomic structure and the ordering behavior of this phase and resolve long-standing discrepancies with the original (2$\\times$2)pg model [Phys. Rev. Lett. 82 (1999) 4874]. We further prove by short-range order simulations that the coherent superposition of scattering contributions of the nano-domains leads to a virtual extinction of diffraction spots, which has concealed the true periodicity and symmetry of this phase for so long.",
