CeSe2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 10-coordinate geometry to four equivalent Se(1) and six equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 4-coordinate geometry to four equivalent Ce(1) atoms. In the second Se site, Se(2) is bonded in a 6-coordinate geometry to six equivalent Ce(1) atoms.
CeSe2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 10-coordinate geometry to four equivalent Se(1) and six equivalent Se(2) atoms. There are two shorter (2.96 Å) and two longer (3.07 Å) Ce(1)-Se(1) bond lengths. There are four shorter (3.13 Å) and two longer (3.52 Å) Ce(1)-Se(2) bond lengths. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 4-coordinate geometry to four equivalent Ce(1) atoms. In the second Se site, Se(2) is bonded in a 6-coordinate geometry to six equivalent Ce(1) atoms.
