Abstract

Ca3Au14Bi crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 12-coordinate geometry to sixteen Au+0.64- atoms. There are a spread of Ca–Au bond distances ranging from 3.26–3.48 Å. In the second Ca2+ site, Ca2+ is bonded in a 12-coordinate geometry to fifteen Au+0.64- atoms. There are a spread of Ca–Au bond distances ranging from 3.25–3.40 Å. In the third Ca2+ site, Ca2+ is bonded in a 9-coordinate geometry to thirteen Au+0.64- atoms. There are a spread of Ca–Au bond distances ranging from 3.27–3.51 Å. There are eight inequivalent Au+0.64- sites. In the first Au+0.64- site, Au+0.64- is bonded to four Ca2+ and twelve Au+0.64- atoms to form distorted AuCa4Au12 tetrahedra that share faces with fifteen AuCa3BiAu8 cuboctahedra and faces with nine AuCa4Au12 tetrahedra. There are a spread of Au–Au bond distances ranging from 3.25–3.35 Å. In the second Au+0.64- site, Au+0.64- is bonded to four Ca2+ and twelve Au+0.64- atoms to form distorted AuCa4Au12 tetrahedra that share corners with three equivalent AuCa3BiAu8 cuboctahedra, a faceface with one AuCa3Bi3Au6 cuboctahedra, and faces with nine AuCa4Au12 tetrahedra.
