The structure described by Rb(SbSe2)2 crystallizes in the triclinic P-1 space group. Rb(1) is bonded in a 10-coordinate geometry to one Se(1), two equivalent Se(4), three equivalent Se(2), and four equivalent Se(3) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted rectangular see-saw-like geometry to one Se(2), one Se(4), and two equivalent Se(1) atoms. In the second Sb site, Sb(2) is bonded in a distorted see-saw-like geometry to one Se(1), one Se(2), one Se(3), and one Se(4) atom. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted rectangular see-saw-like geometry to one Rb(1), one Sb(2), and two equivalent Sb(1) atoms. In the second Se site, Se(2) is bonded in a 5-coordinate geometry to three equivalent Rb(1), one Sb(1), and one Sb(2) atom. In the third Se site, Se(3) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one Sb(2), and one Se(3) atom. In the fourth Se site, Se(4) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
