The structure described by La2Pd2O5 crystallizes in the tetragonal P4_2/m space group. La(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Pd(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent La(1) and two equivalent Pd(1) atoms to form distorted OLa3Pd2 trigonal bipyramids that share corners with four equivalent O(2)La4 tetrahedra, corners with eight equivalent O(1)La3Pd2 trigonal bipyramids,  an edgeedge with one O(2)La4 tetrahedra, edges with five equivalent O(1)La3Pd2 trigonal bipyramids, and  a faceface with one O(1)La3Pd2 trigonal bipyramid. In the second O site, O(2) is bonded to four equivalent La(1) atoms to form OLa4 tetrahedra that share corners with sixteen equivalent O(1)La3Pd2 trigonal bipyramids, edges with two equivalent O(2)La4 tetrahedra, and edges with four equivalent O(1)La3Pd2 trigonal bipyramids. is represented by the CIF file [CIF]
