ErIrO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Er(1) is bonded to twelve equivalent O(1) atoms to form ErO12 cuboctahedra that share corners with twelve equivalent Er(1)O12 cuboctahedra, faces with six equivalent Er(1)O12 cuboctahedra, and faces with eight equivalent Ir(1)O6 octahedra. Ir(1) is bonded to six equivalent O(1) atoms to form IrO6 octahedra that share corners with six equivalent Ir(1)O6 octahedra and faces with eight equivalent Er(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Er(1) and two equivalent Ir(1) atoms to form a mixture of distorted edge, corner, and face-sharing OEr4Ir2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
