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.
