BiOBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one BiOBr sheet oriented in the (0, 0, 1) direction. Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent Br1- atoms. All Bi–O bond lengths are 2.35 Å. All Bi–Br bond lengths are 3.22 Å. O2- is bonded to four equivalent Bi3+ atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. Br1- is bonded in a 4-coordinate geometry to four equivalent Bi3+ atoms.
