Materials Data on LaGd(CuSn)4 by Materials Project

Abstract

GdLa(CuSn)4 crystallizes in the tetragonal P4mm 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 (3.36 Å) and four longer (3.46 Å) Gd–Cu bond lengths. There are four shorter (3.38 Å) and four longer (3.57 Å) Gd–Sn bond lengths. La is bonded in a 12-coordinate geometry to eight Cu and eight Sn atoms. There are four shorter (3.40 Å) and four longer (3.45 Å) La–Cu bond lengths. There are four shorter (3.39 Å) and four longer (3.59 Å) La–Sn bond lengths. There are three inequivalent Cu sites. In the first Cu site, Cu is bonded in a 9-coordinate geometry to four equivalent La and five Sn atoms. There are one shorter (2.55 Å) and four longer (2.67 Å) Cu–Sn bond lengths. 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 (2.52 Å) and four longer (2.65 Å) Cu–Sn bond lengths. In the third Cu site, Cu is bonded in a 12-coordinate geometry to two equivalent Gd, two equivalent La, and four Sn atoms. All Cu–Sn bond lengths are 2.62 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent La and five Cu atoms. In the second Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Gd and five Cu atoms. In the third Sn site, Sn is bonded in a 4-coordinate geometry to two equivalent Gd, two equivalent La, and four Cu atoms.
