The structure described by GdRe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded in a 12-coordinate geometry to three equivalent Re(1) and nine equivalent Re(2) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to six equivalent Gd(1) and six equivalent Re(2) atoms to form a mixture of edge, corner, and face-sharing ReGd6Re6 cuboctahedra. In the second Re site, Re(2) is bonded to six equivalent Gd(1), two equivalent Re(1), and four equivalent Re(2) atoms to form a mixture of edge, corner, and face-sharing ReGd6Re6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
