MgTbO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra and faces with eight equivalent Tb(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Tb(1) is bonded to twelve equivalent O(1) atoms to form TbO12 cuboctahedra that share corners with twelve equivalent Tb(1)O12 cuboctahedra, faces with six equivalent Tb(1)O12 cuboctahedra, and faces with eight equivalent Mg(1)O6 octahedra. O(1) is bonded in a distorted linear geometry to two equivalent Mg(1) and four equivalent Tb(1) atoms.
