Materials Data on GdFeB4 by Materials Project
GdFeB4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Gd3+ is bonded in a 4-coordinate geometry to fourteen B+1.50- atoms. There are a spread of Gd–B bond distances ranging from 2.60–2.72 Å. Fe3+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Fe–B bond distances ranging from 2.21–2.29 Å. There are four inequivalent B+1.50- sites. In the first B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Gd3+, two equivalent Fe3+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.73–1.82 Å. In the second B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Gd3+, two equivalent Fe3+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.73–1.86 Å. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Gd3+, two equivalent Fe3+, and three B+1.50- atoms. In the fourth B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to two equivalent Gd3+, four equivalent Fe3+, and three B+1.50- atoms. The B–B bond length is 1.69 Å.
