The material described by Yb2ZnTe2(SO7)2 crystallizes in the triclinic P-1 space group. Yb(1) is bonded to one O(1), one O(4), one O(5), one O(6), one O(7), and two equivalent O(3) atoms to form distorted YbO7 pentagonal bipyramids that share corners with three equivalent S(1)O4 tetrahedra,  an edgeedge with one Zn(1)O6 octahedra, and  an edgeedge with one Yb(1)O7 pentagonal bipyramid. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(6) atoms to form ZnO6 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 distorted T-shaped geometry to one O(1), one O(3), and one O(6) atom. S(1) is bonded to one O(2), one O(4), one O(5), and one O(7) atom to form SO4 tetrahedra that share  a cornercorner with one Zn(1)O6 octahedra and corners with three equivalent Yb(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 49°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Yb(1), one Zn(1), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one S(1) atom. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to two equivalent Yb(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Yb(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Yb(1) and one S(1) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Yb(1), one Zn(1), and one Te(1) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Yb(1) and one S(1) atom. is represented by the CIF card [CIF]
