Materials Data on Gd3BBr3 by Materials Project
Gd3BBr3 is Corundum-derived structured and crystallizes in the cubic I4_132 space group. The structure is three-dimensional. Gd is bonded to two equivalent B and four equivalent Br atoms to form a mixture of corner and edge-sharing GdB2Br4 octahedra. The corner-sharing octahedra tilt angles range from 7–11°. Both Gd–B bond lengths are 2.63 Å. There are two shorter (2.97 Å) and two longer (3.09 Å) Gd–Br bond lengths. B is bonded to six equivalent Gd atoms to form edge-sharing BGd6 octahedra. Br is bonded in a rectangular see-saw-like geometry to four equivalent Gd atoms.
