The material structure described by La2PdO4 crystallizes in the tetragonal I4/mmm space group. La(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Pd(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent La(1) and two equivalent Pd(1) atoms to form OLa4Pd2 octahedra that share corners with two equivalent O(2)La4Pd2 octahedra, corners with twelve equivalent O(1)La4 tetrahedra, edges with two equivalent O(2)La4Pd2 octahedra, edges with two equivalent O(1)La4 tetrahedra, and faces with four equivalent O(2)La4Pd2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(1) is bonded to four equivalent La(1) atoms to form OLa4 tetrahedra that share corners with twelve equivalent O(2)La4Pd2 octahedra, corners with four equivalent O(1)La4 tetrahedra, edges with two equivalent O(2)La4Pd2 octahedra, and edges with four equivalent O(1)La4 tetrahedra. The corner-sharing octahedral tilt angles range from 12-69°. is represented by the Crystallographic Information File (CIF) [CIF]
