Materials Data on BeGe2Te by Materials Project

Abstract

BeGe2Te crystallizes in the cubic F-43m space group. The structure is three-dimensional. Be is bonded to four equivalent Te atoms to form distorted corner-sharing BeTe4 tetrahedra. All Be–Te bond lengths are 2.94 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a body-centered cubic geometry to four equivalent Ge and four equivalent Te atoms. All Ge–Ge bond lengths are 2.94 Å. All Ge–Te bond lengths are 2.94 Å. In the second Ge site, Ge is bonded in a distorted body-centered cubic geometry to four equivalent Ge atoms. Te is bonded in a body-centered cubic geometry to four equivalent Be and four equivalent Ge atoms.
