GeO2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form corner-sharing GeO4 tetrahedra. In the second Ge site, Ge(2) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form corner-sharing GeO4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Ge(2) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ge(1) and one Ge(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Ge(1) and one Ge(2) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Ge(1) and one Ge(2) atom.
