The title compound, [Cu(C6H2Br3O)(2)(NH3)(2)], a monomeric centrosymmetric Cu-II complex, crystallizes in the monoclinic system. The CuO2N2 coordination sphere is trans planar, [Cu-O 1.943 (5) Angstrom and Cu-N 1.977 (6) Angstrom], with the fifth and sixth coordination sites occupied by Br atoms from the phenoxide ions [Cu-Br 3.129 (1) Angstrom], resulting in an elongated distorted octahedral structure for the CuO2N2Br2 coordination. Each of the NH3 groups forms two hydrogen bonds with the Br and O atoms of the CuO2N2Br2 moiety of a neighbouring molecule. This arrangement constitutes a one-dimensional chain along the x axis of the unit cell.
