CsCeCuS3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Cs–S bond distances ranging from 3.53–3.80 Å. Ce3+ is bonded to six S2- atoms to form CeS6 octahedra that share corners with two equivalent CeS6 octahedra, edges with two equivalent CeS6 octahedra, and edges with four equivalent CuS4 tetrahedra. The corner-sharing octahedral tilt angles are 33°. There are two shorter (2.73 Å) and four longer (2.75 Å) Ce–S bond lengths. Cu2+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with two equivalent CuS4 tetrahedra and edges with four equivalent CeS6 octahedra. There are two shorter (2.31 Å) and two longer (2.42 Å) Cu–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to two equivalent Cs1+, two equivalent Ce3+, and two equivalent Cu2+ atoms. In the second S2- site, S2- is bonded in a 6-coordinate geometry to three equivalent Cs1+, two equivalent Ce3+, and one Cu2+ atom.
