NaSbTe2 crystallizes in the tetragonal P4/mmm space group. Na(1) is bonded to two equivalent Te(1) and four equivalent Te(2) atoms to form NaTe6 octahedra that share corners with six equivalent Na(1)Te6 octahedra, edges with four equivalent Na(1)Te6 octahedra, and edges with eight equivalent Sb(1)Te6 octahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded to two equivalent Te(2) and four equivalent Te(1) atoms to form SbTe6 octahedra that share corners with six equivalent Sb(1)Te6 octahedra, edges with four equivalent Sb(1)Te6 octahedra, and edges with eight equivalent Na(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 Na(1) and four equivalent Sb(1) atoms to form distorted TeNa2Sb4 octahedra that share corners with six equivalent Te(1)Na2Sb4 octahedra, edges with four equivalent Te(1)Na2Sb4 octahedra, and edges with eight equivalent Te(2)Na4Sb2 octahedra. The corner-sharing octahedra are not tilted. In the second Te site, Te(2) is bonded to four equivalent Na(1) and two equivalent Sb(1) atoms to form TeNa4Sb2 octahedra that share corners with six equivalent Te(2)Na4Sb2 octahedra, edges with four equivalent Te(2)Na4Sb2 octahedra, and edges with eight equivalent Te(1)Na2Sb4 octahedra. The corner-sharing octahedra are not tilted.
