	abstract = {A crystallographic analysis is reported using low-energy electron diffraction (LEED) in the tensor LEED approach for the electrodeposited coadsorption (3 x 3) structure with 4/9 monolayer (ML) of silver and 4/9 ML of iodine on the Pt(1 1 1) surface. The structure approximates a two-layer slice of bulk AgI cut parallel to its (1 1 1) plane and superimposed on the substrate with the Ag atoms in contact with the topmost Pt(1 1 1) layer, and the I atoms forming an overlayer on the Ag atoms. There are two types of Ag atoms in the (3 x 3) unit mesh; one type bonds to a single Pt atom, while the other type bonds to three Pt atoms. The average Ag-Pt bond distances are close to 2.48 and 2.82 (A) over circle respectively for the one and three-coordinate Ag atoms, but both types of Ag atoms bond to three I atoms with an average Ag-I distance of 2.67 (A) over circle. No significant corrugation is observed for either the I layer or the Ag layer. (C) 2001 Elsevier Science B.V. All rights reserved.},

	abstract = {Three distinct ordered iodine structures on a Pt(lll) surface have been studied with LEED crystallography in the coverage range 0.33-0.44 monolayers. These surfaces have translational symmetries of the ((root 3 x root 3)R30 degrees, (root 7 x root 7)R19.1 degrees and (3 x 3) types, and they all involve overlayer adsorption on the basically unreconstructed metal structures. The root 3 surface phase is indicated to have essentially all I atoms adsorbed at the regular threefold sites of the fee type (i.e. 3f sites), with no significant involvement by the corresponding sites of the hcp type (i.e. 3h sites). The root 7 structure has one I on an atop Pt site, and one each at 3f and 3h sites per unit mesh, while the (3 x 3) surface has one I on an atop site and three on bridge sites per unit mesh. The I corrugation is about 0.5 Angstrom for the root 7 structure, but is reduced to around 0.1 Angstrom at the (3 x 3) surface. The surface I-Pt bond lengths from these analyses show a general tendency to follow trends expected with the varying I coordination numbers. A preliminary discussion is given for uncertainties associated with some relaxations indicated in the metallic structures.},
