CaAu4Bi crystallizes in the cubic F-43m space group. Ca(1) is bonded in a 16-coordinate geometry to twelve equivalent Au(1) and four equivalent Bi(1) atoms. Au(1) is bonded to three equivalent Ca(1), six equivalent Au(1), and three equivalent Bi(1) atoms to form a mixture of edge, face, and corner-sharing AuCa3Bi3Au6 cuboctahedra. Bi(1) is bonded in a 16-coordinate geometry to four equivalent Ca(1) and twelve equivalent Au(1) atoms.
CaAu4Bi crystallizes in the cubic F-43m space group. Ca(1) is bonded in a 16-coordinate geometry to twelve equivalent Au(1) and four equivalent Bi(1) atoms. All Ca(1)-Au(1) bond lengths are 3.31 Å. All Ca(1)-Bi(1) bond lengths are 3.46 Å. Au(1) is bonded to three equivalent Ca(1), six equivalent Au(1), and three equivalent Bi(1) atoms to form a mixture of edge, face, and corner-sharing AuCa3Bi3Au6 cuboctahedra. There are three shorter (2.82 Å) and three longer (2.84 Å) Au(1)-Au(1) bond lengths. All Au(1)-Bi(1) bond lengths are 3.32 Å. Bi(1) is bonded in a 16-coordinate geometry to four equivalent Ca(1) and twelve equivalent Au(1) atoms.
