The structure described by Eu2CoTe2(SO7)2 crystallizes in the triclinic P-1 space group. Eu(1) is bonded to one O(1), one O(3), one O(6), one O(7), two equivalent O(4), and two equivalent O(5) atoms to form distorted EuO8 hexagonal bipyramids that share corners with two equivalent S(1)O4 tetrahedra, edges with two equivalent Eu(1)O8 hexagonal bipyramids,  an edgeedge with one Co(1)O6 octahedra, and  an edgeedge with one S(1)O4 tetrahedra. Co(1) is bonded to two equivalent O(2), two equivalent O(6), and two equivalent O(7) atoms to form CoO6 octahedra that share corners with two equivalent S(1)O4 tetrahedra and edges with two equivalent Eu(1)O8 hexagonal bipyramids. 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 corners with two equivalent Eu(1)O8 hexagonal bipyramids,  a cornercorner with one Co(1)O6 octahedra, and  an edgeedge with one Eu(1)O8 hexagonal bipyramid. The corner-sharing octahedral tilt angles are 43°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Eu(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Eu(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Eu(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to two equivalent Eu(1) and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Eu(1), one Co(1), and one Te(1) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Eu(1), one Co(1), and one Te(1) atom. is represented by the CIF file [CIF]
