The crystal structure described by WGe2O6 crystallizes in the monoclinic P2_1/c space group. W(1) is bonded to one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form WO6 octahedra that share corners with three equivalent Ge(1)O4 tetrahedra, corners with three equivalent Ge(2)O4 tetrahedra, and edges with two equivalent W(1)O6 octahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(4), one O(5), and two equivalent O(2) 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 43-58°. In the second Ge site, Ge(2) is bonded to one O(3), one O(6), 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(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-60°. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Ge(2) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Ge(2) atoms. In the third O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Ge(1) atoms. In the fourth O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one Ge(2) atom. In the fifth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one W(1) and one Ge(1) atom. In the sixth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Ge(1) atom. is represented by the CIF file [CIF]
