Cd2SiO4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Cd(1) is bonded to six equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Si(1)O4 tetrahedra and edges with six equivalent Cd(1)O6 octahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with twelve equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. O(1) is bonded in a 4-coordinate geometry to three equivalent Cd(1) and one Si(1) atom.
