Materials Data on RbGeSbO5 by Materials Project
RbGeSbO5 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.78–3.31 Å. In the second Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.79–3.37 Å. 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 four SbO6 octahedra. The corner-sharing octahedra tilt angles range from 46–55°. There are a spread of Ge–O bond distances ranging from 1.77–1.79 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four SbO6 octahedra. The corner-sharing octahedra tilt angles range from 50–54°. There is three shorter (1.77 Å) and one longer (1.78 Å) Ge–O bond length. There are two inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of Sb–O bond distances ranging from 1.99–2.05 Å. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of Sb–O bond distances ranging from 1.99–2.06 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ge4+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Ge4+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ge4+, and one Sb5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ge4+, and one Sb5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ge4+, and one Sb5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ge4+, and one Sb5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ge4+, and one Sb5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+ and two Sb5+ atoms. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to two Rb1+, one Ge4+, and one Sb5+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to two Rb1+ and two Sb5+ atoms.
