Materials Data on Gd by Materials Project

Abstract

Gd is alpha Samarium structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are four inequivalent Gd sites. In the first Gd site, Gd is bonded to twelve Gd atoms to form a mixture of face, edge, and corner-sharing GdGd12 cuboctahedra. There are six shorter (3.57 Å) and six longer (3.62 Å) Gd–Gd bond lengths. In the second Gd site, Gd is bonded to twelve Gd atoms to form a mixture of face, edge, and corner-sharing GdGd12 cuboctahedra. There are three shorter (3.57 Å) and six longer (3.62 Å) Gd–Gd bond lengths. In the third Gd site, Gd is bonded to twelve Gd atoms to form a mixture of face, edge, and corner-sharing GdGd12 cuboctahedra. There are six shorter (3.57 Å) and six longer (3.62 Å) Gd–Gd bond lengths. In the fourth Gd site, Gd is bonded to twelve Gd atoms to form a mixture of face, edge, and corner-sharing GdGd12 cuboctahedra. There are six shorter (3.57 Å) and six longer (3.62 Å) Gd–Gd bond lengths.
