Materials Data on LuBi2BrO4 by Materials Project
LuBi2O4Br is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Lu3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Lu–O bond lengths are 2.36 Å. Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent Br1- atoms. All Bi–O bond lengths are 2.25 Å. All Bi–Br bond lengths are 3.49 Å. O2- is bonded to two equivalent Lu3+ and two equivalent Bi3+ atoms to form a mixture of edge and corner-sharing OLu2Bi2 tetrahedra. Br1- is bonded in a body-centered cubic geometry to eight equivalent Bi3+ atoms.
