title: [μ-N,N,N',N'-Tetra-kis(2-pyridyl-meth-yl)butane-1,4-diamine]-bis-[dibromidocopper(II)].
abstract: The title dinuclear copper complex, [Cu(2)Br(4)(C(28)H(32)N(6))], is located on an inversion center. The unique Cu(II) ion is in a slightly distorted square-pyramidal environment in which the N atoms of a dipicolyl-amine group and a bromide ligand form the basal plane. The apical site is occupied by a second Br atom. While the Cu-N distances involving the pyridine N atoms are the same within experimental error, the Cu-N distance involving the tertiary N atom is slightly elongated. Due to the typical Jahn-Teller distortion of copper(II) complexes, the apical Cu-Br distance is elongated.
