ThV2O6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Th(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form ThO6 octahedra that share corners with eight equivalent V(1)O6 octahedra and edges with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-56°. V(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form VO6 octahedra that share corners with four equivalent Th(1)O6 octahedra, corners with four equivalent V(1)O6 octahedra,  an edgeedge with one Th(1)O6 octahedra, and  an edgeedge with one V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 3-coordinate geometry to one Th(1) and two equivalent V(1) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to one Th(1) and two equivalent V(1) atoms.

The corner-sharing octahedral tilt angles range from 53-56°. Both Th(1)-O(1) bond lengths are 2.22 Å. All Th(1)-O(2) bond lengths are 2.36 Å. V(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form VO6 octahedra that share corners with four equivalent Th(1)O6 octahedra, corners with four equivalent V(1)O6 octahedra,  an edgeedge with one Th(1)O6 octahedra, and  an edgeedge with one V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. Both V(1)-O(1) bond lengths are 1.97 Å. There are two shorter (1.88 Å) and two longer (2.14 Å) V(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 3-coordinate geometry to one Th(1) and two equivalent V(1) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to one Th(1) and two equivalent V(1) atoms.
