The structure described by RbTl3O5 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. There are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded to one O(1), one O(3), two equivalent O(4), and two equivalent O(5) atoms to form a mixture of edge and corner-sharing TlO6 octahedra. The corner-sharing octahedral tilt angles range from 9-56°. In the second Tl site, Tl(2) is bonded to one O(4), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of edge and corner-sharing TlO6 octahedra. The corner-sharing octahedral tilt angles range from 7-9°. In the third Tl site, Tl(3) is bonded to one O(2), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of distorted edge and corner-sharing TlO6 octahedra. The corner-sharing octahedral tilt angles range from 7-56°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Tl(3), and two equivalent Tl(1) atoms. In the second O site, O(1) is bonded to one Tl(1), two equivalent Tl(3), and three equivalent Tl(2) atoms to form OTl6 octahedra that share corners with three equivalent O(3)RbTl3 trigonal pyramids, edges with four equivalent O(1)Tl6 octahedra, and  an edgeedge with one O(3)RbTl3 trigonal pyramid. In the third O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Tl(3), and two equivalent Tl(2) atoms. In the fourth O site, O(3) is bonded to one Rb(1), one Tl(1), and two equivalent Tl(3) atoms to form distorted ORbTl3 trigonal pyramids that share corners with three equivalent O(1)Tl6 octahedra, corners with two equivalent O(3)RbTl3 trigonal pyramids, and  an edgeedge with one O(1)Tl6 octahedra. The corner-sharing octahedral tilt angles range from 12-13°. In the fifth O site, O(4) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Tl(2), and two equivalent Tl(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
