The compound described by Tm2CuTe2(SO7)2 crystallizes in the triclinic P-1 space group. Tm(1) is bonded in a 8-coordinate geometry to one O(1), one O(3), one O(6), one O(7), two equivalent O(4), and two equivalent O(5) atoms. Cu(1) is bonded to two equivalent O(2), two equivalent O(6), and two equivalent O(7) atoms to form CuO6 octahedra that share corners with two equivalent S(1)O4 tetrahedra. Te(1) is bonded in a distorted T-shaped geometry to one O(5), one O(6), and one O(7) atom. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share  a cornercorner with one Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Tm(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Tm(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Tm(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Tm(1) and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Tm(1), one Cu(1), and one Te(1) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one Tm(1), one Cu(1), and one Te(1) atom. is represented by the CIF file [CIF]
