DyAgTe2 crystallizes in the trigonal P3m1 space group. Dy(1) is bonded to three equivalent Te(1) and three equivalent Te(2) atoms to form DyTe6 octahedra that share corners with six equivalent Ag(1)Te4 tetrahedra, edges with six equivalent Dy(1)Te6 octahedra, and edges with three equivalent Ag(1)Te4 tetrahedra. Ag(1) is bonded to one Te(1) and three equivalent Te(2) atoms to form AgTe4 tetrahedra that share corners with six equivalent Dy(1)Te6 octahedra, corners with six equivalent Ag(1)Te4 tetrahedra, and edges with three equivalent Dy(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 11-58°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to three equivalent Dy(1) and one Ag(1) atom to form distorted TeDy3Ag trigonal pyramids that share corners with six equivalent Te(2)Dy3Ag3 octahedra, corners with six equivalent Te(1)Dy3Ag trigonal pyramids, and edges with three equivalent Te(2)Dy3Ag3 octahedra. The corner-sharing octahedral tilt angles range from 3-66°. In the second Te site, Te(2) is bonded to three equivalent Dy(1) and three equivalent Ag(1) atoms to form TeDy3Ag3 octahedra that share corners with six equivalent Te(1)Dy3Ag trigonal pyramids, edges with six equivalent Te(2)Dy3Ag3 octahedra, and edges with three equivalent Te(1)Dy3Ag trigonal pyramids.
