The structure described by CeSe2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pbcn space group. Ce(1) is bonded to six equivalent Se(1) atoms to form a mixture of corner and edge-sharing CeSe6 octahedra. The corner-sharing octahedral tilt angles are 51°. Se(1) is bonded in a trigonal planar geometry to three equivalent Ce(1) atoms. is represented by the CIF file [CIF]
