Materials Data on RbAu(SeO4)2 by Materials Project
RbAu(SeO4)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.95–3.41 Å. Au5+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.03 Å. Se5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.64 Å) and two longer (1.75 Å) Se–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Se5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one Se5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Au5+, and one Se5+ atom.
