catena-Poly[[μ-bromido-(μ-hydroxydi-2-pyridylmethano­lato-κ(4) N,O:O,N′)dicopper(II)(Cu—Cu)]-di-μ-bromido]

The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) 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—H⋯O hydrogen bonds are present in the crystal structure.
