LaPdO4 crystallizes in the trigonal R-3m space group. La(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Pd(1) is bonded to two equivalent O(1) and six equivalent O(2) atoms to form edge-sharing PdO8 hexagonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent La(1) and one Pd(1) atom to form OLa3Pd tetrahedra that share corners with ten equivalent O(1)La3Pd tetrahedra, corners with six equivalent O(2)LaPd3 trigonal pyramids, edges with three equivalent O(1)La3Pd tetrahedra, and edges with three equivalent O(2)LaPd3 trigonal pyramids. In the second O site, O(2) is bonded to one La(1) and three equivalent Pd(1) atoms to form OLaPd3 trigonal pyramids that share corners with six equivalent O(1)La3Pd tetrahedra, corners with ten equivalent O(2)LaPd3 trigonal pyramids, edges with three equivalent O(1)La3Pd tetrahedra, and edges with three equivalent O(2)LaPd3 trigonal pyramids.
LaPdO4 crystallizes in the trigonal R-3m space group. La(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both La(1)-O(2) bond lengths are 2.81 Å. All La(1)-O(1) bond lengths are 2.44 Å. Pd(1) is bonded to two equivalent O(1) and six equivalent O(2) atoms to form edge-sharing PdO8 hexagonal bipyramids. Both Pd(1)-O(1) bond lengths are 2.02 Å. All Pd(1)-O(2) bond lengths are 2.24 Å. There are two inequivalent O sites.
