The monoclinic crystal structure of Bi4O5Br2 has been determined from 1:1 twinned crystals pretending orthorhombic symmetry. Bi4O5Br2 crystallizes with space group P21 (no. 4), Z=4, a=14.539(4), b=5.605(1), c=10.782(3) Å, β= 97.75(7)o. Its structure shows much closer relationships to the structure of α-Bi5O7I than to that one of the homologuous compound Bi4O5Cl2.
