SiO2 is low (alpha) Cristobalite structured and crystallizes in the tetragonal P4_12_12 space group. Si(1) is bonded to four equivalent O(1) atoms to form corner-sharing SiO4 tetrahedra. O(1) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms.
SiO2 is low (alpha) Cristobalite structured and crystallizes in the tetragonal P4_12_12 space group. Si(1) is bonded to four equivalent O(1) atoms to form corner-sharing SiO4 tetrahedra. All Si(1)-O(1) bond lengths are 1.61 Å. O(1) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms.
