Materials Data on CaBiAu4 by Materials Project
CaAu4Bi is beta-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ca2+ is bonded in a 12-coordinate geometry to twelve equivalent Au1- atoms. All Ca–Au bond lengths are 3.35 Å. Au1- is bonded to three equivalent Ca2+, six equivalent Au1-, and three equivalent Bi2+ atoms to form a mixture of face, edge, and corner-sharing AuCa3Bi3Au6 cuboctahedra. There are three shorter (2.85 Å) and three longer (2.86 Å) Au–Au bond lengths. All Au–Bi bond lengths are 3.35 Å. Bi2+ is bonded in a 12-coordinate geometry to twelve equivalent Au1- atoms.
