The crystal structure described by HfCdF7Tl crystallizes in the orthorhombic Cmcm space group. The structure consists of four 7440-28-0 atoms inside a HfCdF7 framework. In the HfCdF7 framework, Hf(1) is bonded to one F(2), two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form HfF7 pentagonal bipyramids that share corners with three equivalent Cd(1)F7 pentagonal bipyramids and edges with two equivalent Cd(1)F7 pentagonal bipyramids. Cd(1) is bonded to one F(2), two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form CdF7 pentagonal bipyramids that share corners with three equivalent Hf(1)F7 pentagonal bipyramids and edges with two equivalent Hf(1)F7 pentagonal bipyramids. There are four inequivalent F sites. In the first F site, F(1) is bonded in a water-like geometry to one Hf(1) and one Cd(1) atom. In the second F site, F(2) is bonded in a linear geometry to one Hf(1) and one Cd(1) atom. In the third F site, F(3) is bonded in a linear geometry to one Hf(1) and one Cd(1) atom. In the fourth F site, F(4) is bonded in a bent 120 degrees geometry to one Hf(1) and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
