Materials Data on CaSiO3 by Materials Project
CaSiO3 is (Cubic) Perovskite-like structured and crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Ca2+ is bonded to twelve O2- atoms to form CaO12 cuboctahedra that share corners with twelve equivalent CaO12 cuboctahedra, faces with six equivalent CaO12 cuboctahedra, and faces with eight equivalent SiO6 octahedra. There are a spread of Ca–O bond distances ranging from 2.47–2.64 Å. Si4+ is bonded to six O2- atoms to form SiO6 octahedra that share corners with six equivalent SiO6 octahedra and faces with eight equivalent CaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–8°. There is four shorter (1.80 Å) and two longer (1.81 Å) Si–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ca2+ and two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ca2+ and two equivalent Si4+ atoms.
