Rb2U(PdS2)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 S(1) and four equivalent S(2) atoms. In the second Rb site, Rb(2) is bonded in a 10-coordinate geometry to two equivalent S(2) and eight equivalent S(1) atoms. U(1) is bonded in a 6-coordinate geometry to two equivalent S(2) and four equivalent S(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 S(1) and two equivalent S(2) atoms. In the second Pd site, Pd(2) is bonded in a square co-planar geometry to four equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Rb(1), two equivalent Rb(2), one U(1), one Pd(1), and one Pd(2) atom to form a mixture of distorted corner, face, and edge-sharing SRb3UPd2 octahedra. The corner-sharing octahedral tilt angles range from 6-96°. In the second S site, S(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 corner, face, and edge-sharing SRb3UPd2 octahedra. The corner-sharing octahedral tilt angles range from 6-79°.
