Materials Data on Gd2SnAu2 by Materials Project
Gd2Au2Sn crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Gd is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent Sn atoms. There are two shorter (2.98 Å) and four longer (3.10 Å) Gd–Au bond lengths. All Gd–Sn bond lengths are 3.53 Å. Au is bonded in a 9-coordinate geometry to six equivalent Gd, one Au, and two equivalent Sn atoms. The Au–Au bond length is 2.83 Å. Both Au–Sn bond lengths are 3.13 Å. Sn is bonded to eight equivalent Gd and four equivalent Au atoms to form a mixture of face and corner-sharing SnGd8Au4 cuboctahedra.
