The structure described by GdOs2 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 Os(1) and nine equivalent Os(2) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to six equivalent Gd(1) and six equivalent Os(2) atoms to form a mixture of edge, face, and corner-sharing OsGd6Os6 cuboctahedra. In the second Os site, Os(2) is bonded to six equivalent Gd(1), two equivalent Os(1), and four equivalent Os(2) atoms to form a mixture of edge, face, and corner-sharing OsGd6Os6 cuboctahedra. is represented by the CIF card [CIF]
