Abstract

Au4Hg crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are five inequivalent Au+0.50- sites. In the first Au+0.50- site, Au+0.50- is bonded to nine Au+0.50- and three equivalent Hg2+ atoms to form a mixture of distorted edge, corner, and face-sharing AuHg3Au9 cuboctahedra. There are three shorter (2.90 Å) and six longer (3.06 Å) Au–Au bond lengths. All Au–Hg bond lengths are 3.03 Å. In the second Au+0.50- site, Au+0.50- is bonded to twelve Au+0.50- atoms to form a mixture of edge, corner, and face-sharing AuAu12 cuboctahedra. There are three shorter (2.89 Å) and six longer (3.06 Å) Au–Au bond lengths. In the third Au+0.50- site, Au+0.50- is bonded to twelve Au+0.50- atoms to form a mixture of edge, corner, and face-sharing AuAu12 cuboctahedra. There are three shorter (2.90 Å) and six longer (3.06 Å) Au–Au bond lengths. In the fourth Au+0.50- site, Au+0.50- is bonded to twelve Au+0.50- atoms to form a mixture of edge, corner, and face-sharing AuAu12 cuboctahedra. There are a spread of Au–Au bond distances ranging from 2.89–3.06 Å. In the fifth Au+0.50- site, Au+0.50- is bonded to twelve Au+0.50- atoms to form a mixture of edge, corner, and face-sharing AuAu12 cuboctahedra. Theremore »« less
