Materials Data on Rb3Sb2Au3 by Materials Project
Rb3Au3Sb2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent Au1- atoms. All Rb–Au bond lengths are 4.14 Å. In the second Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to six equivalent Au1- and one Sb atom. All Rb–Au bond lengths are 3.79 Å. The Rb–Sb bond length is 3.66 Å. Au1- is bonded in a distorted linear geometry to six Rb1+ and two equivalent Sb atoms. Both Au–Sb bond lengths are 2.69 Å. Sb is bonded in a 4-coordinate geometry to one Rb1+ and three equivalent Au1- atoms.
