The material described by Y2CoTe2(SO7)2 crystallizes in the triclinic P-1 space group. Y(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), one O(5), one O(6), two equivalent O(1), and two equivalent O(7) atoms. Co(1) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with two equivalent S(1)O4 tetrahedra. Te(1) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(5) atom. S(1) is bonded to one O(3), one O(4), one O(6), and one O(7) atom to form SO4 tetrahedra that share  a cornercorner with one Co(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 trigonal non-coplanar geometry to two equivalent Y(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Y(1), one Co(1), and one Te(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Y(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Y(1), one Co(1), and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted water-like geometry to one Y(1) and one S(1) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
