Materials Data on K2Be2PbF8 by Materials Project
K2Be2PbF8 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten F1- atoms. There are a spread of K–F bond distances ranging from 2.58–2.87 Å. Be2+ is bonded in a tetrahedral geometry to four F1- atoms. There is one shorter (1.55 Å) and three longer (1.58 Å) Be–F bond length. Pb2+ is bonded in a 12-coordinate geometry to six equivalent F1- atoms. All Pb–F bond lengths are 2.59 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to three equivalent K1+, one Be2+, and one Pb2+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to one K1+ and one Be2+ atom.
