The structure described by CeSe2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Ce(1) is bonded in a 12-coordinate geometry to twelve equivalent Se(1) atoms. Se(1) is bonded to six equivalent Ce(1) and six equivalent Se(1) atoms to form a mixture of edge, corner, and face-sharing SeCe6Se6 cuboctahedra. is represented by the CIF card [CIF]
