N2 - The atomic geometry of the CuCl(110)-(1×1) surface is determined by dynamical analysis of low-energy electron-diffraction intensities. This surface undergoes a relaxation characterized by a 30°Cu-Cl surface bond rotation, a 0.15 contraction of the top-to-second layer distance, and a 0.4 horizontal displacement of Cl relative to Cu. The relaxation is consistent with the eeuniversalee structure deduced from the analysis of cleavage surface of tetrahedrally coordinated III-V and II-VI compounds, thereby revealing that this featuare of the structure does not depend significntly on the ionicity of the compound.
