CeNiSi is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Ce(1) is bonded to six equivalent Ni(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing CeSi6Ni6 cuboctahedra. Ni(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 Ni(1) atoms.
