CeSe2 is quartz (alpha) structured and crystallizes in the trigonal P3_121 space group. Ce(1) is bonded to four equivalent Se(1) atoms to form corner-sharing CeSe4 tetrahedra. Se(1) is bonded in a bent 120 degrees geometry to two equivalent Ce(1) atoms.
CeSe2 is quartz (alpha) structured and crystallizes in the trigonal P3_121 space group. Ce(1) is bonded to four equivalent Se(1) atoms to form corner-sharing CeSe4 tetrahedra. All Ce(1)-Se(1) bond lengths are 2.73 Å. Se(1) is bonded in a bent 120 degrees geometry to two equivalent Ce(1) atoms.
