Materials Data on HeSiO2 by Materials Project
Abstract
HeSiO2 is High (Orthorhombic) Tridymite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of eight helium molecules and one SiO2 framework. In the SiO2 framework, there are two inequivalent Si sites. In the first Si site, Si is bonded to four O atoms to form corner-sharing SiO4 tetrahedra. All Si–O bond lengths are 1.62 Å. In the second Si site, Si is bonded to four O atoms to form corner-sharing SiO4 tetrahedra. All Si–O bond lengths are 1.62 Å. There are four inequivalent O sites. In the first O site, O is bonded in a linear geometry to two Si atoms. In the second O site, O is bonded in a linear geometry to two Si atoms. In the third O site, O is bonded in a bent 150 degrees geometry to two equivalent Si atoms. In the fourth O site, O is bonded in a bent 150 degrees geometry to two equivalent Si atoms.
