The material structure described by WGeO4 crystallizes in the monoclinic P2/c space group. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted WO6 octahedra that share corners with eight equivalent Ge(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-57°. Ge(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted GeO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Ge(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-57°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent W(1) and one Ge(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
