Materials Data on KH(IF6)2 by Materials Project

K(IF5)2HF2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional and consists of four hydrogen fluoride hydrogen fluoride molecules and one K(IF5)2 framework. In the K(IF5)2 framework, K1+ is bonded in a 8-coordinate geometry to eight equivalent F1- atoms. All K–F bond lengths are 2.69 Å. I5+ is bonded in a 5-coordinate geometry to five F1- atoms. There is one shorter (1.88 Å) and four longer (1.95 Å) I–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one I5+ atom. In the second F1- site, F1- is bonded in a distorted linear geometry to one K1+ and one I5+ atom.
