ThWTeO7 crystallizes in the monoclinic P2_1/c space group. Th(1) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(4), two equivalent O(5), and two equivalent O(7) atoms. W(1) is bonded to one O(6), one O(7), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 3°. Te(1) is bonded in a 3-coordinate geometry to one O(4), one O(5), and two equivalent O(2) atoms. There are seven inequivalent O sites.
