The structure described by SiO2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pbcn space group. Si(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing SiO6 octahedra. The corner-sharing octahedral tilt angles are 51°. O(1) is bonded in a distorted trigonal planar geometry to three equivalent Si(1) atoms. is represented by the CIF file [CIF]
