The crystal structure described by RbTl3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded in a distorted body-centered cubic geometry to six equivalent Tl(2) and eight equivalent Tl(1) atoms. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded to four equivalent Rb(1) and four equivalent Tl(2) atoms to form a mixture of corner, face, and edge-sharing TlRb4Tl4 tetrahedra. In the second Tl site, Tl(2) is bonded in a 14-coordinate geometry to six equivalent Rb(1) and eight equivalent Tl(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
