SiO2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm 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 49°. O(1) is bonded in a distorted trigonal planar geometry to three equivalent Si(1) atoms.

The corner-sharing octahedral tilt angles are 49°. There are four shorter (1.78 Å) and two longer (1.84 Å) Si(1)-O(1) bond lengths. O(1) is bonded in a distorted trigonal planar geometry to three equivalent Si(1) atoms.
