Materials Data on SiO2 by Materials Project

Kristin Persson
SiO2 is Keatite-like structured and crystallizes in the orthorhombic Cmme space group. The structure is three-dimensional. there are ten inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. All Si–O bond lengths are 1.61 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There is one shorter (1.61 Å) and three longer (1.62 Å) Si–O...
