The material described by Na(SnO2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. Na(1) is bonded to four equivalent O(1) atoms to form NaO4 tetrahedra that share corners with twelve equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 61°. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Na(1)O4 tetrahedra and edges with six equivalent Sn(1)O6 octahedra. O(1) is bonded to one Na(1) and three equivalent Sn(1) atoms to form a mixture of corner and edge-sharing ONaSn3 tetrahedra. is represented by the CIF card [CIF]
