CeSI is Baddeleyite-derived structured and crystallizes in the orthorhombic Pbca space group. Ce(1) is bonded in a 7-coordinate geometry to four equivalent S(1) and three equivalent I(1) atoms. S(1) is bonded to four equivalent Ce(1) atoms to form a mixture of edge and corner-sharing SCe4 tetrahedra. I(1) is bonded in a distorted trigonal planar geometry to three equivalent Ce(1) atoms.
