In this paper we presented the X-ray PDF investigation of orthorhombic Ba2In2O5 and cubic Ba2In1.7P0.3O5.3 and Ba2In1.7S0.3O5.45 samples. Pure Ba2In2O5 was found to be properly described-at the local scale-by the orthorhombic average structure. Ba2In1.7P0.3O5.3 and Ba2In1.7S0.3O5.45 cannot be described, at the local scale, by a cubic symmetry. The PDFs of these two samples clearly showed a distorted atom arrangement in the short-range which can be described again with the orthorhombic symmetry found in pure barium indate.
