All Au–Bi bond lengths are 3.34 Å. In the seventh Au1- site, Au1- is bonded to three equivalent Ca2+, six Au1-, and three equivalent Bi2+ atoms to form a mixture of corner, edge, and face-sharing AuCa3Bi3Au6 cuboctahedra. All Au–Bi bond lengths are 3.36 Å. In the eighth Au1- site, Au1- is bonded to six Au1- and six Bi2+ atoms to form AuBi6Au6 cuboctahedra that share corners with eighteen AuCa3Bi3Au6 cuboctahedra, edges with six equivalent AuBi6Au6 cuboctahedra, and faces with eighteen AuCaBi5Au6 cuboctahedra. All Au–Au bond lengths are 2.88 Å. There are three shorter (3.33 Å) and three longer (3.34 Å) Au–Bi bond lengths. In the ninth Au1- site, Au1- is bonded to two equivalent Ca2+, six Au1-, and four Bi2+ atoms to form a mixture of corner, edge, and face-sharing AuCa2Bi4Au6 cuboctahedra. All Au–Au bond lengths are 2.85 Å. There are a spread of Au–Bi bond distances ranging from 3.35–3.40 Å.
