Materials Data on Rb2Li2SiO4 by Materials Project
Rb2Li2SiO4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.93–3.26 Å. In the second Rb1+ site, Rb1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.80–3.37 Å. There are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.16 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with two equivalent SiO4 tetrahedra, an edgeedge with one LiO4 tetrahedra, and an edgeedge with one SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.02 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and an edgeedge with one LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.69 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to four Rb1+, two Li1+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Rb1+, three Li1+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to six Rb1+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Rb1+, three Li1+, and one Si4+ atom.
