Materials Data on BeGe3 by Materials Project

Abstract

BeGe3 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Be is bonded in a distorted square co-planar geometry to twelve Ge atoms. There are four shorter (2.78 Å) and eight longer (2.95 Å) Be–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded to four equivalent Be and eight Ge atoms to form a mixture of distorted face, edge, and corner-sharing GeBe4Ge8 cuboctahedra. There are four shorter (2.78 Å) and four longer (2.95 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a distorted square co-planar geometry to four equivalent Be and eight equivalent Ge atoms.
