The structure described by Rb2U(PtSe2)3 crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to four equivalent Se(1) and four equivalent Se(2) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent Se(2) and four equivalent Se(1) atoms. U(1) is bonded in a 6-coordinate geometry to two equivalent Se(2) and four equivalent Se(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted square co-planar geometry to two equivalent Se(1) and two equivalent Se(2) atoms. In the second Pt site, Pt(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Se(1) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 5-coordinate geometry to one Rb(1), one Rb(2), one U(1), one Pt(1), and one Pt(2) atom. In the second Se site, Se(2) is bonded to one Rb(2), two equivalent Rb(1), one U(1), and two equivalent Pt(1) atoms to form a mixture of distorted corner, edge, and face-sharing SeRb3UPt2 octahedra. The corner-sharing octahedral tilt angles range from 29-78°. is represented by the CIF card [CIF]
