Materials Data on Y2CdS4 by Materials Project

CdY2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Y3+ is bonded to six equivalent S2- atoms to form YS6 octahedra that share corners with six equivalent CdS4 tetrahedra and edges with six equivalent YS6 octahedra. All Y–S bond lengths are 2.75 Å. Cd2+ is bonded to four equivalent S2- atoms to form CdS4 tetrahedra that share corners with twelve equivalent YS6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Cd–S bond lengths are 2.59 Å. S2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Y3+ and one Cd2+ atom.
