Materials Data on Rb2Ga2Ge3O10 by Materials Project
Abstract
Rb2Ga2Ge3O10 crystallizes in the monoclinic C2 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 O2- atoms. There are a spread of Rb–O bond distances ranging from 2.82–3.17 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.49 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with three GeO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.80–2.02 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with four GeO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.86–1.88 Å. There are four 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 GaO4 tetrahedra and corners with two equivalent GeO4 tetrahedra. There is two shorter (1.75 Å) and two longer (1.80 Å) Ge–O bondmore »
