Materials Data on Be2Re by Materials Project
Be2Re is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Be sites. In the first Be site, Be is bonded to six equivalent Be and six equivalent Re atoms to form a mixture of face, edge, and corner-sharing BeBe6Re6 cuboctahedra. All Be–Be bond lengths are 2.20 Å. All Be–Re bond lengths are 2.57 Å. In the second Be site, Be is bonded to six Be and six equivalent Re atoms to form a mixture of face, edge, and corner-sharing BeBe6Re6 cuboctahedra. There are two shorter (2.16 Å) and two longer (2.22 Å) Be–Be bond lengths. There are two shorter (2.56 Å) and four longer (2.57 Å) Be–Re bond lengths. Re is bonded in a 12-coordinate geometry to twelve Be and four equivalent Re atoms. There are three shorter (2.68 Å) and one longer (2.69 Å) Re–Re bond lengths.
