Rb2U(OCl)4 crystallizes in the triclinic P-1 space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent Cl(1), and three equivalent Cl(2) atoms. U(1) is bonded in a distorted octahedral geometry to two equivalent O(1), two equivalent Cl(1), and two equivalent Cl(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 in a water-like geometry to two equivalent Rb(1) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one U(1) atom. In the second Cl site, Cl(2) is bonded to three equivalent Rb(1) and one U(1) atom to form a mixture of distorted edge and corner-sharing ClRb3U trigonal pyramids.
