Materials Data on AcBrO by Materials Project
AcOBr is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. 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 Å. There are four shorter (3.42 Å) and one longer (3.65 Å) Ac–Br bond lengths. O2- is bonded to four equivalent Ac3+ atoms to form a mixture of edge and corner-sharing OAc4 tetrahedra. Br1- is bonded in a 5-coordinate geometry to five equivalent Ac3+ atoms.
