RESUMEN
The crystal structure of the title complex, [Cu(2)Br(3)(OH)(C(11)H(13)Br(0.5)Cl(1.5)N(2)O)(2)], consists of two (2-halo-6-oxazolin-yl)pyridine·CuBr units bridged by a Br atom and a hydroxide group. The Cu(II) atoms are five-coordinate with an (N,N)BrCu(Br)(OH) distorted tetra-gonal-pyramidal core, and relatively short contacts to the bridging atoms (Cu-µ-OH and Cu-µ-Br). There are two symmetry-independent half-mol-ecules in the asymmetric unit, which differ only in the arrangement of the isopropyl group. The mol-ecules are located on a twofold rotation axes.
