NaSbTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Na(1) is bonded to six equivalent Te(1) atoms to form NaTe6 octahedra that share corners with six equivalent Sb(1)Te6 octahedra, edges with six equivalent Na(1)Te6 octahedra, and edges with six equivalent Sb(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 4°. Sb(1) is bonded to six equivalent Te(1) atoms to form SbTe6 octahedra that share corners with six equivalent Na(1)Te6 octahedra, edges with six equivalent Na(1)Te6 octahedra, and edges with six equivalent Sb(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 4°. Te(1) is bonded to three equivalent Na(1) and three equivalent Sb(1) atoms to form a mixture of corner and edge-sharing TeNa3Sb3 octahedra. The corner-sharing octahedra are not tilted.
