Materials Data on NdBr3 by Materials Project
NdBr3 crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two NdBr3 sheets oriented in the (0, 1, 0) direction. Nd3+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Nd–Br bond distances ranging from 2.92–3.18 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Nd3+ atoms. In the second Br1- site, Br1- is bonded in an L-shaped geometry to two equivalent Nd3+ atoms.
