The material structure described by GeO2 is low (alpha) Cristobalite structured and crystallizes in the tetragonal P4_12_12 space group. Ge(1) is bonded to four equivalent O(1) atoms to form corner-sharing GeO4 tetrahedra. O(1) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
