Materials Data on Rb2MgSi5O12 by Materials Project
Abstract
Rb2MgSi5O12 crystallizes in the orthorhombic Pbca 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 2.86–3.51 Å. In the second Rb1+ site, Rb1+ is bonded in a 2-coordinate geometry to four O2- atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.44 Å. Mg2+ is bonded to four O2- atoms to form MgO4 tetrahedra that share corners with four SiO4 tetrahedra. There are a spread of Mg–O bond distances ranging from 1.92–1.95 Å. There are five inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one MgO4 tetrahedra and corners with three SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.58–1.68 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one MgO4 tetrahedra and corners with three SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.58–1.66 Å. In the third Si4+ site, Si4+more »
