TlTeVO5 crystallizes in the orthorhombic Pna2_1 space group. V(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms. Tl(1) is bonded in a 5-coordinate geometry to one O(5), two equivalent O(1), and two equivalent O(2) atoms. Te(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(5), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent V(1) and two equivalent Tl(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to one V(1), two equivalent Tl(1), and one Te(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one V(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent Te(1) atoms. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one V(1), one Tl(1), and one Te(1) atom.
