The structure described by AcOBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ac(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and five equivalent Br(1) atoms. O(1) is bonded to four equivalent Ac(1) atoms to form a mixture of corner and edge-sharing OAc4 tetrahedra. Br(1) is bonded in a 5-coordinate geometry to five equivalent Ac(1) atoms. is represented by the CIF file [CIF]
