CaSnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional and consists of one tin powder molecule and one CaO3 framework. In the CaO3 framework, Ca2+ is bonded to six equivalent O2- atoms to form corner-sharing CaO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ca–O bond lengths are 2.17 Å. O2- is bonded in a linear geometry to two equivalent Ca2+ atoms.
