The material structure described by Ca(DyTe2)2 crystallizes in the monoclinic P2/m space group. Ca(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form CaTe6 octahedra that share corners with six equivalent Dy(1)Te6 octahedra, edges with two equivalent Ca(1)Te6 octahedra, edges with two equivalent Dy(1)Te6 octahedra, and edges with four equivalent Dy(2)Te6 octahedra. The corner-sharing octahedral tilt angles range from 2-3°. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form DyTe6 octahedra that share corners with six equivalent Ca(1)Te6 octahedra, edges with two equivalent Ca(1)Te6 octahedra, edges with two equivalent Dy(1)Te6 octahedra, and edges with four equivalent Dy(2)Te6 octahedra. The corner-sharing octahedral tilt angles range from 2-3°. In the second Dy site, Dy(2) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form DyTe6 octahedra that share edges with two equivalent Dy(2)Te6 octahedra, edges with four equivalent Ca(1)Te6 octahedra, and edges with four equivalent Dy(1)Te6 octahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ca(1), one Dy(2), and two equivalent Dy(1) atoms to form a mixture of edge and corner-sharing TeCa2Dy3 square pyramids. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to one Ca(1), one Dy(1), and two equivalent Dy(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
