Materials Data on SrCdSi by Materials Project
SrCdSi is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Sr2+ is bonded in a distorted body-centered cubic geometry to four equivalent Cd2+ and four equivalent Si4- atoms. All Sr–Cd bond lengths are 3.16 Å. All Sr–Si bond lengths are 3.16 Å. Cd2+ is bonded to four equivalent Sr2+ atoms to form CdSr4 tetrahedra that share corners with four equivalent SiSr4 tetrahedra, corners with twelve equivalent CdSr4 tetrahedra, and edges with six equivalent SiSr4 tetrahedra. Si4- is bonded to four equivalent Sr2+ atoms to form SiSr4 tetrahedra that share corners with four equivalent CdSr4 tetrahedra, corners with twelve equivalent SiSr4 tetrahedra, and edges with six equivalent CdSr4 tetrahedra.
