K(IF5)2HF2 crystallizes in the tetragonal I4/mcm space group. The structure consists of four hydrogen fluoride hydrogen fluoride molecules inside a K(IF5)2 framework. In the K(IF5)2 framework, K(1) is bonded in a 8-coordinate geometry to eight equivalent F(3) atoms. I(1) is bonded in a distorted square pyramidal geometry to one F(2) and four equivalent F(3) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a single-bond geometry to one I(1) atom. In the second F site, F(3) is bonded in a distorted linear geometry to one K(1) and one I(1) atom.
