Rb2TlOCl5 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 7-coordinate geometry to one Cl(3), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(4) atoms. Tl(1) is bonded in a 6-coordinate geometry to one O(1), one Cl(1), one Cl(2), one Cl(3), and two equivalent Cl(4) atoms. O(1) is bonded in a distorted single-bond geometry to one Tl(1) and one Cl(3) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent Rb(1) and one Tl(1) atom to form a mixture of distorted edge, corner, and face-sharing ClRb4Tl square pyramids. In the second Cl site, Cl(2) is bonded to four equivalent Rb(1) and one Tl(1) atom to form a mixture of distorted edge, corner, and face-sharing ClRb4Tl square pyramids. In the third Cl site, Cl(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Tl(1), and one O(1) atom. In the fourth Cl site, Cl(4) is bonded in a 1-coordinate geometry to two equivalent Rb(1) and one Tl(1) atom.
