The crystal structure described by LiSbSe2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded to six Se(1,1,1,1) atoms to form LiSe6 octahedra that share corners with two equivalent Sb(1)Se6 octahedra, corners with four equivalent Li(1)Se6 octahedra, edges with four equivalent Li(1)Se6 octahedra, and edges with eight equivalent Sb(1)Se6 octahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded to six Se(1,1,1,1) atoms to form SbSe6 octahedra that share corners with two equivalent Li(1)Se6 octahedra, corners with four equivalent Sb(1)Se6 octahedra, edges with four equivalent Sb(1)Se6 octahedra, and edges with eight equivalent Li(1)Se6 octahedra. The corner-sharing octahedra are not tilted. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded to three equivalent Li(1) and three equivalent Sb(1) atoms to form a mixture of corner and edge-sharing SeLi3Sb3 octahedra. The corner-sharing octahedra are not tilted. In the second Se site, Se(1) is bonded to three equivalent Li(1) and three equivalent Sb(1) atoms to form a mixture of corner and edge-sharing SeLi3Sb3 octahedra. The corner-sharing octahedra are not tilted. In the third Se site, Se(1) is bonded to three equivalent Li(1) and three equivalent Sb(1) atoms to form a mixture of corner and edge-sharing SeLi3Sb3 octahedra. The corner-sharing octahedra are not tilted. In the fourth Se site, Se(1) is bonded to three equivalent Li(1) and three equivalent Sb(1) atoms to form a mixture of corner and edge-sharing SeLi3Sb3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
