The material structure described by Sm2ZnTe2(SO7)2 crystallizes in the triclinic P-1 space group. Sm(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. Zn(1) is bonded to two equivalent O(2), two equivalent O(6), and two equivalent O(7) atoms to form ZnO6 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 Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Sm(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Sm(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Sm(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 Sm(1) and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Sm(1), one Zn(1), and one Te(1) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one Sm(1), one Zn(1), and one Te(1) atom. is represented by the CIF card [CIF]
