The compound described by WGe2O6 crystallizes in the monoclinic C2/c space group. W(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with two equivalent W(1)O6 octahedra. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent W(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 38-59°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(1) and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
