Materials Data on Yb2CdS4 by Materials Project
CdYb2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Yb3+ is bonded to six equivalent S2- atoms to form YbS6 octahedra that share corners with six equivalent CdS4 tetrahedra and edges with six equivalent YbS6 octahedra. All Yb–S bond lengths are 2.78 Å. Cd2+ is bonded to four equivalent S2- atoms to form CdS4 tetrahedra that share corners with twelve equivalent YbS6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Cd–S bond lengths are 2.55 Å. S2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Yb3+ and one Cd2+ atom.
