Materials Data on Gd2CBr by Materials Project

Gd2CBr is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Gd is bonded to three equivalent C and three equivalent Br atoms to form a mixture of distorted corner, edge, and face-sharing GdC3Br3 octahedra. The corner-sharing octahedra tilt angles range from 0–40°. All Gd–C bond lengths are 2.51 Å. All Gd–Br bond lengths are 3.15 Å. C is bonded to six equivalent Gd atoms to form edge-sharing CGd6 octahedra. Br is bonded in a 6-coordinate geometry to six equivalent Gd atoms.

Materials Data on GdCBr by Materials Project

GdCBr crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one GdCBr sheet oriented in the (0, 0, 1) direction. Gd3+ is bonded in a 8-coordinate geometry to five equivalent C2- and three equivalent Br1- atoms. There are a spread of Gd–C bond distances ranging from 2.37–2.69 Å. There are two shorter (2.93 Å) and one longer (3.08 Å) Gd–Br bond lengths. C2- is bonded in a 6-coordinate geometry to five equivalent Gd3+ and one C2- atom. The C–C bond length is 1.33 Å. Br1- is bonded in a 3-coordinate geometry to three equivalent Gd3+ atoms.
