Materials Data on Sc2CdSe4 by Materials Project

Sc2CdSe4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Sc3+ is bonded to six equivalent Se2- atoms to form ScSe6 octahedra that share corners with six equivalent CdSe4 tetrahedra and edges with six equivalent ScSe6 octahedra. All Sc–Se bond lengths are 2.73 Å. Cd2+ is bonded to four equivalent Se2- atoms to form CdSe4 tetrahedra that share corners with twelve equivalent ScSe6 octahedra. The corner-sharing octahedral tilt angles are 58°. All Cd–Se bond lengths are 2.67 Å. Se2- is bonded to three equivalent Sc3+ and one Cd2+ atom to form a mixture of distorted edge and corner-sharing SeSc3Cd trigonal pyramids.
