Materials Data on LaCBr by Materials Project
LaCBr crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one LaCBr sheet oriented in the (0, 0, 1) direction. La3+ is bonded in a 8-coordinate geometry to five equivalent C2- and three equivalent Br1- atoms. There are a spread of La–C bond distances ranging from 2.51–2.84 Å. There are two shorter (3.07 Å) and one longer (3.18 Å) La–Br bond lengths. C2- is bonded in a 2-coordinate geometry to five equivalent La3+ and one C2- atom. The C–C bond length is 1.32 Å. Br1- is bonded in a 3-coordinate geometry to three equivalent La3+ atoms.
