Materials Data on LuBr3 by Materials Project
LuBr3 crystallizes in the hexagonal P6_3/mmc space group. The structure is one-dimensional and consists of two LuBr3 ribbons oriented in the (0, 0, 1) direction. Lu3+ is bonded to six equivalent Br1- atoms to form distorted face-sharing LuBr6 pentagonal pyramids. All Lu–Br bond lengths are 2.77 Å. Br1- is bonded in an L-shaped geometry to two equivalent Lu3+ atoms.
