The compound described by SiO2 is alpha Selenium structured and crystallizes in the trigonal P3_221 space group. The structure is zero-dimensional and consists of three dtxsid70587853 molecules. Si(1) is bonded in a bent 120 degrees geometry to two equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to one Si(1) atom. is represented by the CIF card [CIF]
