AcOBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ac3+ is bonded in a 4-coordinate geometry to four equivalent O2- and five equivalent Br1- atoms. All ˚ Ac–O bond lengths are 2.49 A. ˚There are four shorter (3.40 A)˚ and one longer (3.54 A) Ac–Br bond length. O2- is bonded to four equivalent Ac3+ atoms to form a mixture of corner and edge-sharing OAc4 tetrahedra. Br1- is bonded in a 5-coordinate geometry to five equivalent Ac3+ atoms.
