The structure described by CeCrS3 crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 9-coordinate geometry to two equivalent S(1), three equivalent S(2), and four equivalent S(3) atoms. Cr(1) is bonded to one S(3), two equivalent S(2), and three equivalent S(1) atoms to form edge-sharing CrS6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Ce(1) and three equivalent Cr(1) atoms. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent Ce(1) and two equivalent Cr(1) atoms. In the third S site, S(3) is bonded to four equivalent Ce(1) and one Cr(1) atom to form a mixture of distorted corner and edge-sharing SCe4Cr square pyramids. is represented by the CIF file [CIF]
