The structure described by Rb2U(PdSe2)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 10-coordinate geometry to two equivalent Se(2) and eight 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 Pd sites. In the first Pd site, Pd(1) is bonded in a square co-planar geometry to two equivalent Se(1) and two equivalent Se(2) atoms. In the second Pd site, Pd(2) is bonded in a square co-planar geometry to four equivalent Se(1) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 6-coordinate geometry to one Rb(1), two equivalent Rb(2), one U(1), one Pd(1), and one Pd(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 Pd(1) atoms to form a mixture of distorted face, corner, and edge-sharing SeRb3UPd2 octahedra. The corner-sharing octahedral tilt angles range from 28-79°. is represented by the CIF file [CIF]
