CeSe2 is Hydrophilite-like structured and crystallizes in the tetragonal P4_12_12 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 range from 42-61°. Se(1) is bonded in a distorted trigonal planar geometry to three equivalent Ce(1) atoms.

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 range from 42-61°. There are a spread of Ce(1)-Se(1) bond distances ranging from 2.85-2.89 Å. Se(1) is bonded in a distorted trigonal planar geometry to three equivalent Ce(1) atoms.
