Materials Data on LaBr2 by Materials Project
LaBr2 is Molybdenite-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two LaBr2 sheets oriented in the (0, 0, 1) direction. La2+ is bonded to six equivalent Br1- atoms to form distorted edge-sharing LaBr6 pentagonal pyramids. All La–Br bond lengths are 3.07 Å. Br1- is bonded in a distorted T-shaped geometry to three equivalent La2+ atoms.
