LiEuS2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Li(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form LiS6 octahedra that share corners with six equivalent Li(1)S6 octahedra, edges with four equivalent Li(1)S6 octahedra, and edges with eight equivalent Eu(1)S6 octahedra. The corner-sharing octahedra are not tilted. Eu(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form EuS6 octahedra that share corners with six equivalent Eu(1)S6 octahedra, edges with four equivalent Eu(1)S6 octahedra, and edges with eight equivalent Li(1)S6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Li(1) and four equivalent Eu(1) atoms to form SLi2Eu4 octahedra that share corners with six equivalent S(1)Li2Eu4 octahedra, edges with four equivalent S(1)Li2Eu4 octahedra, and edges with eight equivalent S(2)Li4Eu2 octahedra. The corner-sharing octahedra are not tilted. In the second S site, S(2) is bonded to four equivalent Li(1) and two equivalent Eu(1) atoms to form SLi4Eu2 octahedra that share corners with six equivalent S(2)Li4Eu2 octahedra, edges with four equivalent S(2)Li4Eu2 octahedra, and edges with eight equivalent S(1)Li2Eu4 octahedra. The corner-sharing octahedra are not tilted.
