Abstract

SiO2 is quartz (alpha)-like structured and crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. there are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four equivalent O2- atoms to form corner-sharing SiO4 tetrahedra. All Si–O bond lengths are 1.63 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.64 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two Si4+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Si4+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms.

SiO2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two water molecules and one Si8O15 framework. In the Si8O15 framework, there are eight inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There is three shorter (1.62 Å) and one longer (1.63 Å) Si–O bond length. In the second Si4+ site, Si4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.64 Å) and one longer (1.65 Å) Si–O bond length. In the third Si4+ site, Si4+more »« less
