EuPbTe2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Eu(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form EuTe6 octahedra that share corners with six equivalent Eu(1)Te6 octahedra, edges with four equivalent Eu(1)Te6 octahedra, and edges with eight equivalent Pb(1)Te6 octahedra. The corner-sharing octahedra are not tilted. Pb(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form PbTe6 octahedra that share corners with six equivalent Pb(1)Te6 octahedra, edges with four equivalent Pb(1)Te6 octahedra, and edges with eight equivalent Eu(1)Te6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Eu(1) and four equivalent Pb(1) atoms to form TeEu2Pb4 octahedra that share corners with six equivalent Te(1)Eu2Pb4 octahedra, edges with four equivalent Te(1)Eu2Pb4 octahedra, and edges with eight equivalent Te(2)Eu4Pb2 octahedra. The corner-sharing octahedra are not tilted. In the second Te site, Te(2) is bonded to four equivalent Eu(1) and two equivalent Pb(1) atoms to form TeEu4Pb2 octahedra that share corners with six equivalent Te(2)Eu4Pb2 octahedra, edges with four equivalent Te(2)Eu4Pb2 octahedra, and edges with eight equivalent Te(1)Eu2Pb4 octahedra. The corner-sharing octahedra are not tilted.
