Materials Data on GdRe2 by Materials Project
GdRe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Gd is bonded in a 12-coordinate geometry to twelve Re atoms. There are a spread of Gd–Re bond distances ranging from 3.17–3.20 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded to six equivalent Gd and six equivalent Re atoms to form a mixture of face, edge, and corner-sharing ReGd6Re6 cuboctahedra. All Re–Re bond lengths are 2.74 Å. In the second Re site, Re is bonded to six equivalent Gd and six Re atoms to form a mixture of face, edge, and corner-sharing ReGd6Re6 cuboctahedra. There are two shorter (2.66 Å) and two longer (2.80 Å) Re–Re bond lengths.
