Materials Data on EuErO3 by Materials Project

ErEuO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er3+ is bonded to six equivalent O2- atoms to form ErO6 octahedra that share corners with six equivalent ErO6 octahedra and faces with eight equivalent EuO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Er–O bond lengths are 2.15 Å. Eu3+ is bonded to twelve equivalent O2- atoms to form EuO12 cuboctahedra that share corners with twelve equivalent EuO12 cuboctahedra, faces with six equivalent EuO12 cuboctahedra, and faces with eight equivalent ErO6 octahedra. All Eu–O bond lengths are 3.04 Å. O2- is bonded in a linear geometry to two equivalent Er3+ and four equivalent Eu3+ atoms.
