The compound described by BeTlF4Tl is Iron carbide-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four 7440-28-0 atoms and four BeTlF4 clusters. In each BeTlF4 cluster, Be(1) is bonded in a tetrahedral geometry to one F(1), one F(2), and two equivalent F(3) atoms. Tl(2) is bonded in a distorted single-bond geometry to one F(1) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one Be(1) and one Tl(2) atom. In the second F site, F(2) is bonded in a single-bond geometry to one Be(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to one Be(1) atom. is represented by the CIF card [CIF]
