Materials Data on CsYCdSe3 by Materials Project
CsYCdSe3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Cs–Se bond distances ranging from 3.70–3.92 Å. Y3+ is bonded to six Se2- atoms to form YSe6 octahedra that share corners with two equivalent YSe6 octahedra, edges with two equivalent YSe6 octahedra, and edges with four equivalent CdSe4 tetrahedra. The corner-sharing octahedral tilt angles are 39°. There are four shorter (2.93 Å) and two longer (2.98 Å) Y–Se bond lengths. Cd2+ is bonded to four Se2- atoms to form CdSe4 tetrahedra that share corners with two equivalent CdSe4 tetrahedra and edges with four equivalent YSe6 octahedra. There are two shorter (2.62 Å) and two longer (2.70 Å) Cd–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 6-coordinate geometry to two equivalent Cs1+, two equivalent Y3+, and two equivalent Cd2+ atoms. In the second Se2- site, Se2- is bonded in a 6-coordinate geometry to three equivalent Cs1+, two equivalent Y3+, and one Cd2+ atom.
