Materials Data on CaSbAu by Materials Project
CaAuSb crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent Au1+ and six equivalent Sb3- atoms to form a mixture of distorted edge and face-sharing CaSb6Au6 cuboctahedra. All Ca–Au bond lengths are 3.41 Å. All Ca–Sb bond lengths are 3.41 Å. Au1+ is bonded in a trigonal planar geometry to six equivalent Ca2+ and three equivalent Sb3- atoms. All Au–Sb bond lengths are 2.71 Å. Sb3- is bonded in a 3-coordinate geometry to six equivalent Ca2+ and three equivalent Au1+ atoms.
