Abstract

Gd2Fe14B crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. there are two inequivalent Gd sites. In the first Gd site, Gd is bonded in a 6-coordinate geometry to sixteen Fe atoms. There are a spread of Gd–Fe bond distances ranging from 3.01–3.22 Å. In the second Gd site, Gd is bonded in a 1-coordinate geometry to sixteen Fe and one B atom. There are a spread of Gd–Fe bond distances ranging from 3.05–3.36 Å. The Gd–B bond length is 2.86 Å. There are six inequivalent Fe sites. In the first Fe site, Fe is bonded to two Gd and ten Fe atoms to form a mixture of distorted face, edge, and corner-sharing FeGd2Fe10 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.37–2.63 Å. In the second Fe site, Fe is bonded to four Gd and eight Fe atoms to form a mixture of face and corner-sharing FeGd4Fe8 cuboctahedra. All Fe–Fe bond lengths are 2.55 Å. In the third Fe site, Fe is bonded in a distorted L-shaped geometry to two equivalent Gd, four Fe, and two equivalent B atoms. There are two shorter (2.50 Å) and two longer (2.76 Å) Fe–Fe bond lengths. Bothmore »« less
