The crystal structure described by Yb2CuTe2(SO7)2 crystallizes in the triclinic P-1 space group. Yb(1) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and two equivalent O(7) atoms to form distorted YbO7 pentagonal bipyramids that share corners with three equivalent S(1)O4 tetrahedra,  an edgeedge with one Cu(1)O6 octahedra, and  an edgeedge with one Yb(1)O7 pentagonal bipyramid. Cu(1) is bonded to two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms to form CuO6 octahedra that share corners with two equivalent S(1)O4 tetrahedra and edges with two equivalent Yb(1)O7 pentagonal bipyramids. Te(1) is bonded in a 3-coordinate 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 and corners with three equivalent Yb(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 53°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Yb(1) and one S(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Yb(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Yb(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to one Yb(1), one Cu(1), and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Yb(1), one Cu(1), and one Te(1) atom. In the seventh O site, O(7) is bonded in a trigonal non-coplanar geometry to two equivalent Yb(1) and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
