The crystal structure described by CeSe2 is Fluorite structured and crystallizes in the orthorhombic Pmmn 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 Crystallographic Information File (CIF) [CIF]
