Materials Data on Al2CdO4 by Materials Project
CdAl2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Cd2+ is bonded to four equivalent O2- atoms to form CdO4 tetrahedra that share corners with twelve equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 62°. All Cd–O bond lengths are 2.14 Å. Al3+ is bonded to six equivalent O2- atoms to form AlO6 octahedra that share corners with six equivalent CdO4 tetrahedra and edges with six equivalent AlO6 octahedra. All Al–O bond lengths are 1.96 Å. O2- is bonded to one Cd2+ and three equivalent Al3+ atoms to form a mixture of distorted edge and corner-sharing OAl3Cd tetrahedra.
