Ca(SnO2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. Ca(1) is bonded to four equivalent O(1) atoms to form CaO4 tetrahedra that share corners with twelve equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Ca(1)O4 tetrahedra and edges with six equivalent Sn(1)O6 octahedra. O(1) is bonded to one Ca(1) and three equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing OCaSn3 trigonal pyramids.
