The structure described by TmAgTe2 crystallizes in the trigonal P3m1 space group. Tm(1) is bonded to three equivalent Te(1) and three equivalent Te(2) atoms to form TmTe6 octahedra that share corners with six equivalent Ag(1)Te4 tetrahedra, edges with six equivalent Tm(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 Tm(1)Te6 octahedra, corners with six equivalent Ag(1)Te4 tetrahedra, and edges with three equivalent Tm(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 9-58°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to three equivalent Tm(1) and one Ag(1) atom to form distorted TeTm3Ag trigonal pyramids that share corners with six equivalent Te(2)Tm3Ag3 octahedra, corners with six equivalent Te(1)Tm3Ag trigonal pyramids, and edges with three equivalent Te(2)Tm3Ag3 octahedra. The corner-sharing octahedral tilt angles range from 3-64°. In the second Te site, Te(2) is bonded to three equivalent Tm(1) and three equivalent Ag(1) atoms to form TeTm3Ag3 octahedra that share corners with six equivalent Te(1)Tm3Ag trigonal pyramids, edges with six equivalent Te(2)Tm3Ag3 octahedra, and edges with three equivalent Te(1)Tm3Ag trigonal pyramids. is represented by the CIF file [CIF]
