The material structure described by CeGeSi is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Ce(1) is bonded to six equivalent Ge(1) and six equivalent Si(1) atoms to form a mixture of edge and face-sharing CeSi6Ge6 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Ge(1) atoms. is represented by the CIF file [CIF]
