The surface structure of Rh(111)-(√3 × √3)R30°-Cl has been investigated by surface extended X-ray absorption fine structure (EXAFS). A nearest neighbour Cl-Rh bond length of 2.38 ± 0.04 angstrom was found, although the adsorption site could not be unambiguously determined. The surface structure of Rh(111)-(√3 × √3)R30°-I was also studied by the normal incidence X-ray standing wavefield (NIXSW) technique. Iodine was found to adsorb predominantly in the 'fcc' hollow site, with at most 10% of atoms in the 'hcp' site.
