Ca2TiSiO6 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 Ti(1)O6 octahedra, and faces with four equivalent Si(1)O6 octahedra. Ti(1) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Si(1)O6 octahedra and faces with eight equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Si(1) is bonded to six equivalent O(1) atoms to form SiO6 octahedra that share corners with six equivalent Ti(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 Ti(1), and one Si(1) atom.
