Materials Data on K2BeF4 by Materials Project
K2BeF4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of K–F bond distances ranging from 2.70–3.12 Å. In the second K1+ site, K1+ is bonded in a 1-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.68–3.11 Å. Be2+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of Be–F bond distances ranging from 1.55–1.58 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to five K1+ and one Be2+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to five K1+ and one Be2+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to four K1+ and one Be2+ atom. In the fourth F1- site, F1- is bonded in a distorted single-bond geometry to five K1+ and one Be2+ atom.
