Abstract: The title complex, [Cu₂Br₃(C₁₁H₉N₂O₂)]_n, was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr₂ with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethanediol. The two copper centers are bridged by a bromide ion and the alkoxy O atom, and the Cu-Cu distance is 2.9801 (5) Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-HO hydrogen bonds are present in the crystal structure.
