Ce3SiS2 is Caswellsilverite-like structured and crystallizes in the orthorhombic Immm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Si(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing CeSi2S4 octahedra. The corner-sharing octahedra are not tilted. In the second Ce site, Ce(2) is bonded to two equivalent Si(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing CeSi2S4 octahedra. The corner-sharing octahedra are not tilted. Si(1) is bonded to two equivalent Ce(1) and four equivalent Ce(2) atoms to form SiCe6 octahedra that share corners with two equivalent Si(1)Ce6 octahedra, corners with four equivalent S(1)Ce6 octahedra, edges with two equivalent Si(1)Ce6 octahedra, and edges with ten equivalent S(1)Ce6 octahedra. The corner-sharing octahedra are not tilted. S(1) is bonded to two equivalent Ce(1) and four equivalent Ce(2) atoms to form SCe6 octahedra that share corners with two equivalent Si(1)Ce6 octahedra, corners with four equivalent S(1)Ce6 octahedra, edges with five equivalent Si(1)Ce6 octahedra, and edges with seven equivalent S(1)Ce6 octahedra. The corner-sharing octahedra are not tilted.

In the first Ce site, Ce(1) is bonded to two equivalent Si(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing CeSi2S4 octahedra. The corner-sharing octahedra are not tilted. Both Ce(1)-Si(1) bond lengths are 2.95 Å. All Ce(1)-S(1) bond lengths are 2.96 Å. In the second Ce site, Ce(2) is bonded to two equivalent Si(1) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing CeSi2S4 octahedra. The corner-sharing octahedra are not tilted. Both Ce(2)-Si(1) bond lengths are 2.97 Å. There are two shorter (2.95 Å) and two longer (2.98 Å) Ce(2)-S(1) bond lengths. Si(1) is bonded to two equivalent Ce(1) and four equivalent Ce(2) atoms to form SiCe6 octahedra that share corners with two equivalent Si(1)Ce6 octahedra, corners with four equivalent S(1)Ce6 octahedra, edges with two equivalent Si(1)Ce6 octahedra, and edges with ten equivalent S(1)Ce6 octahedra.
