We have carried out a powder X-ray diffraction investigation on antiferromagnetic Kondo semiconductors CeRu₂Al₁₀ and CeOs₂Al₁₀ at low temperatures and under high pressures as well as the structural investigation on single crystal of these compounds. The results of powder X-ray studies of CeRu₂Al₁₀ and CeOs₂Al₁₀ indicate that these compounds do not have structural transition at its antiferromagnetic ordering temperature. The results of single crystal structural refinement indicate that the b-axis of this crystal structure is insensitive not only to pressure but also to temperature and that the effect of cooling to Ce-Ce distance for CeRu₂Al₁₀ is the same as that for CeOs₂Al₁₀.
