The material structure described by LuCeS3 crystallizes in the orthorhombic Cmcm space group. Lu(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form a mixture of corner and edge-sharing LuS6 octahedra. The corner-sharing octahedral tilt angles are 49°. Ce(1) is bonded in a 8-coordinate geometry to two equivalent S(2) and six equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Lu(1) and three equivalent Ce(1) atoms to form distorted SCe3Lu2 trigonal bipyramids that share corners with four equivalent S(2)Ce2Lu2 tetrahedra, corners with nine equivalent S(1)Ce3Lu2 trigonal bipyramids, edges with three equivalent S(2)Ce2Lu2 tetrahedra, and edges with six equivalent S(1)Ce3Lu2 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent Lu(1) and two equivalent Ce(1) atoms to form distorted SCe2Lu2 tetrahedra that share corners with four equivalent S(2)Ce2Lu2 tetrahedra, corners with eight equivalent S(1)Ce3Lu2 trigonal bipyramids, and edges with six equivalent S(1)Ce3Lu2 trigonal bipyramids. is represented by the CIF file [CIF]
