The material structure described by Ca2TbNiO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Ca(1)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent Ni(1)O6 octahedra. Tb(1) is bonded to six equivalent O(1) atoms to form TbO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Ca(1), one Tb(1), and one Ni(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
