Tl{sub 2}Te{sub 3}O{sub 7} crystallizes with the triclinic symmetry (space group P-1) and the unit cell parameters a = 6.839(1) {angstrom}, b = 7.432(1) {angstrom}, c = 9.920(2) {angstrom}, {alpha} = 92.00(3){degree}, {beta} = 108.95(3){degree}, {gamma} = 112.85(3){degree}, Z = 2. Its crystal structure has been solved from single crystal data to a final R1 = 0.0299. It can be described as a three-dimensional network of Mo{sub 4}E (M = Tl, Te) trigonal bipyramids and TeO{sub 3}E tetrahedra sharing either corners or edges. This network contains diamond-shaped tunnels roughly parallel to the [1 1 1] direction and towards the center, of which are directed the stereochemically active lone pairs E.
