AuSb2 crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Au1- is bonded to six equivalent Sb+0.50+ atoms to form corner-sharing AuSb6 octahedra. The corner-sharing octahedral tilt angles are 63°. All Au–Sb bond lengths are 2.82 Å. Sb+0.50+ is bonded in a trigonal planar geometry to three equivalent Au1- atoms.
AuSb2(XeF6)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one AuSb2(XeF6)2 cluster. Xe is bonded in a single-bond geometry to one Au atom. The Xe–Au bond length is 2.77 Å. Au is bonded in a linear geometry to two equivalent Xe and two equivalent F atoms. Both Au–F bond lengths are 2.18 Å. Sb is bonded in an octahedral geometry to six F atoms. There are a spread of Sb–F bond distances ranging from 1.90–2.04 Å. There are six inequivalent F sites. In the first F site, F is bonded in a distorted bent 150 degrees geometry to one Au and one Sb atom. In the second F site, F is bonded in a single-bond geometry to one Sb atom. In the third F site, F is bonded in a single-bond geometry to one Sb atom. In the fourth F site, F is bonded in a single-bond geometry to one Sb atom. In the fifth F site, F is bonded in a single-bond geometry to one Sb atom. In the sixth F site, F is bonded in a single-bond geometry to one Sb atom.
