The crystal structure of the title compound, Pb2O(OH)Br, has been determined by single-crystal X-ray diffraction. The compound crystallizes in the tetra-gonal space group P42/mcm. The structure consists of [PbO4Br4] square anti-prisms, which form square layers in the ab plane and are stacked alternately along the c-axis direction. The hydroxide site is assigned on the basis of bond-valence-sum calculations.
