ErGaO3 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 Ga(1)O6 octahedra. Ga(1) is bonded to six equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Ga(1)O6 octahedra and faces with eight equivalent Er(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Er(1) and two equivalent Ga(1) atoms.
