Materials Data on RbYbS2O9 by Materials Project
RbYbS2O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Rb–O bond distances ranging from 2.93–3.20 Å. Yb is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Yb–O bond distances ranging from 2.31–2.55 Å. There are two inequivalent S sites. In the first S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. In the second S site, S is bonded in a tetrahedral geometry to four O atoms. There is two shorter (1.47 Å) and two longer (1.51 Å) S–O bond length. There are nine inequivalent O sites. In the first O site, O is bonded in a 1-coordinate geometry to one Rb, one Yb, and one S atom. In the second O site, O is bonded in a distorted bent 150 degrees geometry to one Yb and one S atom. In the third O site, O is bonded in a 1-coordinate geometry to one Rb, one Yb, and one S atom. In the fourth O site, O is bonded in a single-bond geometry to one Rb and one S atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Rb, one Yb, and one S atom. In the sixth O site, O is bonded in a distorted single-bond geometry to one Yb atom. In the seventh O site, O is bonded in a 3-coordinate geometry to one Rb, one Yb, and one S atom. In the eighth O site, O is bonded in a distorted bent 150 degrees geometry to one Yb and one S atom. In the ninth O site, O is bonded in a distorted single-bond geometry to one Rb, one Yb, and one S atom.
