The compound described by Ce(SbSe2)2 crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a 5-coordinate geometry to one Se(1), two equivalent Se(2), and two equivalent Se(3) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted L-shaped geometry to one Sb(1), one Se(1), and two equivalent Se(3) atoms. In the second Sb site, Sb(2) is bonded in a 3-coordinate geometry to one Se(1) and two equivalent Se(3) atoms. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a 2-coordinate geometry to one Ce(1), one Sb(1), and one Sb(2) atom. In the second Se site, Se(2) is bonded in an L-shaped geometry to two equivalent Ce(1) atoms. In the third Se site, Se(3) is bonded in a distorted T-shaped geometry to one Ce(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
