Materials Data on SrBeF4 by Materials Project
SrBeF4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Sr–F bond distances ranging from 2.48–2.82 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 three equivalent Sr2+ and one Be2+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one Be2+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one Be2+ atom. In the fourth F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one Be2+ atom.
