CeSe2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm 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 50°. Se(1) is bonded in a trigonal planar geometry to three equivalent Ce(1) atoms.

The corner-sharing octahedral tilt angles are 50°. There are four shorter (2.86 Å) and two longer (2.88 Å) Ce(1)-Se(1) bond lengths. Se(1) is bonded in a trigonal planar geometry to three equivalent Ce(1) atoms.
