Using C 1s scanned-energy-mode photoelectron diffraction the local adsorption geometry of acetylene on the Si(100)(2x1) surface has been determined and the results are compared with those of a similar study of ethylene adsorption on this surface. Both molecules bond to the surface along the Si-Si dimers with the C-C bonds parallel to the surface such that the C atoms are in off-atop sites relative to the Si dimer atoms. In both cases the Si-Si bond length (2.36+/-0.21 Angstrom, for ethylene and 2.44+/-0.58 Angstrom for acetylene) is compatible only with the dimer remaining intact after adsorption and not with the Si-Si distance of an ideally terminated undimerized Si(100) surface (3.84 Angstrom).
