The structure of the Ni(1 1 0)c(2 x 2)-CN surface phase has been determined by quantitative low energy electron diffraction (LEED). Contrary to earlier suggestions that relatively intense fractional order LEED beams imply that adsorbate-induced Ni surface reconstruction occurs, the results confirm previous findings by scanned-energy mode photoelectron diffraction and medium energy ion scattering that no significant reconstruction occurs. The C-N axis is oriented along an open-packed (100) azimuth, with the molecule lying above a second layer Ni atom; the intramolecular axis is tilted by 23.7 +/- 4.5degrees relative to the surface plane. The adsorption does lead to a substantial (9 +/- 4%) outward relaxation of the outermost Ni layer spacing and small distortions of the outermost layers of the Ni substrate.
