HeSiO2 is High (Orthorhombic) Tridymite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure consists of eight 7440-59-7 atoms inside a SiO2 framework. In the SiO2 framework, there are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing SiO4 tetrahedra. In the second Si site, Si(2) is bonded to one O(1), one O(2), and two equivalent O(4) atoms to form corner-sharing SiO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Si(1) and one Si(2) atom. In the second O site, O(2) is bonded in a linear geometry to one Si(1) and one Si(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Si(2) atoms.
