The material described by V2TlSbO8 crystallizes in the orthorhombic Pnma space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(5), one O(6), and two equivalent O(3) atoms to form VO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-38°. In the second V site, V(2) is bonded to one O(2), one O(4), and two equivalent O(1) atoms to form VO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 19-39°. Tl(1) is bonded in a single-bond geometry to one O(6) atom. Sb(1) is bonded to one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with three equivalent V(1)O4 tetrahedra and corners with three equivalent V(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(2) and one Sb(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one V(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(2) and one Sb(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(1) and one Sb(1) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one V(1) and one Tl(1) atom. is represented by the CIF card [CIF]
