“…Such a coexistence of c(2ϫ2) and p(2ϫ1) phases was found in STM below the optimum annealing temperature needed for the well-ordered c(2ϫ2) structure and at defects and steps. 16 Entire LEED patterns taken at normal primary beam incidence and with the sample at about 130 K were recorded in steps of 0.5 eV in the energy range 40-500 eV by means of a 12-bit digital CCD camera 39 ͑images were sampled 8 times͒. They were stored on a computer for offline evaluation of sufficiently intense beams.…”

“…In most previous studies, the structure was deduced from qualitative low energy electron diffraction ͑LEED͒ [6][7][8][9][10][11] or scanning tunneling microscopy ͑STM͒. 3,[12][13][14][15][16] Adsorption site analysis was carried out mainly by surface extended x-ray-absorption fine structure ͑SEXAFS͒, [17][18][19][20][21][22][23] whereas quantitative structure determinations by LEED ͑Refs. 24 -26͒ or first-principles calculations 27,28 are sparse.…”

We present a detailed investigation of the c(2ϫ2)-Br/Pt(110) adlayer structure supplemented by the analysis of the (1ϫ2) missing-row ͑MR͒ structure of the clean Pt͑110͒ surface. Quantitative low energy electron diffraction analyses and first-principles calculations are in impressive agreement in both cases. The clean surface reconstruction is determined with unprecedented accuracy. For the adsorbate, the analysis retrieves a simple Br-adlayer structure with the Br atoms residing in every second short bridge position on the closepacked Pt rows with the MR reconstruction lifted. The Br-Pt bond length Lϭ2.47 Å is almost equal to the sum of the atomic radii. The substrate below the adsorbate exhibits a contraction of the first layer spacing which amounts to half of that calculated for an unreconstructed clean surface.
