Materials Data on GdCuSn by Materials Project

GdCuSn crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Gd is bonded in a 12-coordinate geometry to six equivalent Cu and six equivalent Sn atoms. There are three shorter (2.97 Å) and three longer (3.49 Å) Gd–Cu bond lengths. There are three shorter (3.13 Å) and three longer (3.29 Å) Gd–Sn bond lengths. Cu is bonded in a 10-coordinate geometry to six equivalent Gd and four equivalent Sn atoms. There are three shorter (2.70 Å) and one longer (3.07 Å) Cu–Sn bond lengths. Sn is bonded in a 10-coordinate geometry to six equivalent Gd and four equivalent Cu atoms.

Materials Data on Gd(CuSn)2 by Materials Project

GdCu2Sn2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Gd is bonded in a 12-coordinate geometry to eight Cu and eight Sn atoms. There are four shorter (3.34 Å) and four longer (3.39 Å) Gd–Cu bond lengths. There are four shorter (3.32 Å) and four longer (3.55 Å) Gd–Sn bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to four equivalent Gd and four equivalent Sn atoms. All Cu–Sn bond lengths are 2.58 Å. In the second Cu site, Cu is bonded in a 9-coordinate geometry to four equivalent Gd and five Sn atoms. There are one shorter (2.50 Å) and four longer (2.63 Å) Cu–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Gd and four equivalent Cu atoms. In the second Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Gd and five Cu atoms.
