SiO2 is Cuprite structured and crystallizes in the cubic Pn-3m space group. Si(1) is bonded to four equivalent O(1) atoms to form corner-sharing SiO4 tetrahedra. O(1) is bonded in a linear geometry to two equivalent Si(1) atoms.
SiO2 is Cuprite structured and crystallizes in the cubic Pn-3m 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 1.65 Å. O(1) is bonded in a linear geometry to two equivalent Si(1) atoms.
