Materials Data on CuPdO2 by Materials Project

PdCuO2 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. Pd2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Pd–O bond lengths are 2.07 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.96 Å. O2- is bonded to two equivalent Pd2+ and two equivalent Cu2+ atoms to form a mixture of edge and corner-sharing OCu2Pd2 tetrahedra.

Materials Data on CuPdO3 by Materials Project

PdCuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pd4+ is bonded to twelve equivalent O2- atoms to form PdO12 cuboctahedra that share corners with twelve equivalent PdO12 cuboctahedra, faces with six equivalent PdO12 cuboctahedra, and faces with eight equivalent CuO6 octahedra. All Pd–O bond lengths are 2.68 Å. Cu2+ is bonded to six equivalent O2- atoms to form CuO6 octahedra that share corners with six equivalent CuO6 octahedra and faces with eight equivalent PdO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cu–O bond lengths are 1.90 Å. O2- is bonded in a linear geometry to four equivalent Pd4+ and two equivalent Cu2+ atoms.
