Materials Data on Rb2Sn(GeO3)3 by Materials Project
Abstract
Rb2Sn(GeO3)3 crystallizes in the trigonal P-3c1 space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.66–3.08 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All Sn–O bond lengths are 2.09 Å. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent GeO4 tetrahedra. There are three shorter (2.08 Å) and three longer (2.10 Å) Sn–O bond lengths. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent SnO6 octahedra and corners with two equivalent GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. There is two shorter (1.75 Å) and two longer (1.83 Å) Ge–O bond length. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent SnO6 octahedra and corners with two GeO4 tetrahedra. Themore »

In the second O2- site, O2- is bonded in a distorted linear geometry to two equivalent Rb1+ and two equivalent Ge4+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+ and two Ge4+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Sn4+, and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Sn4+, and one Ge4+ atom.},
