The crystal structure described by CeSe2 is Fluorite-like structured and crystallizes in the trigonal P3_221 space group. Ce(1) is bonded in a body-centered cubic geometry to eight equivalent Se(1) atoms. Se(1) is bonded to four equivalent Ce(1) atoms to form a mixture of corner and edge-sharing SeCe4 tetrahedra. is represented by the CIF card [CIF]
