NaCeS2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded to six S(1,1,1,1) atoms to form NaS6 octahedra that share corners with two equivalent Ce(1)S6 octahedra, corners with four equivalent Na(1)S6 octahedra, edges with four equivalent Na(1)S6 octahedra, and edges with eight equivalent Ce(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. Ce(1) is bonded to six S(1,1,1) atoms to form CeS6 octahedra that share corners with two equivalent Na(1)S6 octahedra, corners with four equivalent Ce(1)S6 octahedra, edges with four equivalent Ce(1)S6 octahedra, and edges with eight equivalent Na(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. There are four inequivalent S sites. In the first S site, S(1) is bonded to three equivalent Na(1) and three equivalent Ce(1) atoms to form a mixture of edge and corner-sharing SNa3Ce3 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the second S site, S(1) is bonded to three equivalent Na(1) and three equivalent Ce(1) atoms to form a mixture of edge and corner-sharing SNa3Ce3 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the third S site, S(1) is bonded to three equivalent Na(1) and three equivalent Ce(1) atoms to form a mixture of edge and corner-sharing SNa3Ce3 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the fourth S site, S(1) is bonded to three equivalent Na(1) and three equivalent Ce(1) atoms to form a mixture of edge and corner-sharing SNa3Ce3 octahedra. The corner-sharing octahedral tilt angles range from 0-6°.
