Materials Data on GdReB4 by Materials Project

GdReB4 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 2.68–2.82 Å. Re3+ is bonded in a 10-coordinate geometry to ten B+1.50- atoms. There are a spread of Re–B bond distances ranging from 2.33–2.39 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 Re3+, and three B+1.50- atoms. There are a spread of B–B bond distances ranging from 1.83–1.86 Å. In the second B+1.50- site, B+1.50- is bonded in a 3-coordinate geometry to four equivalent Gd3+, two equivalent Re3+, and three B+1.50- atoms. There is one shorter (1.75 Å) and one longer (1.80 Å) B–B bond length. In the third B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to two equivalent Gd3+, four equivalent Re3+, and three B+1.50- atoms. There is one shorter (1.74 Å) and one longer (1.76 Å) B–B bond length. In the fourth B+1.50- site, B+1.50- is bonded in a 9-coordinate geometry to four equivalent Gd3+, two equivalent Re3+, and three B+1.50- atoms.
