The compound described by Rb2U(OBr)4 crystallizes in the triclinic P-1 space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent Br(1), and two equivalent Br(2) atoms. U(1) is bonded in a distorted linear geometry to two equivalent O(1), two equivalent Br(1), and two equivalent Br(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one U(1) atom. In the second O site, O(2) is bonded to two equivalent Rb(1), one Br(1), and one Br(2) atom to form distorted edge-sharing ORb2Br2 trigonal pyramids. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one U(1), and one O(2) atom. In the second Br site, Br(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one U(1), and one O(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
