title: Bis[2,6-bis-(2-meth-oxy-phen-yl)pyridinium] di-μ-bromido-bis-[dibromidocuprate(II)].
abstract: The title salt, (C(19)H(18)NO(2))(2)[Cu(2)Br(6)], was obtained from an attempt to synthesize the copper(II) complex of 2,6-bis-(2-meth-oxy-phen-yl)pyridine (L) from a reaction between CuBr(2) and one equivalent of L in CH(2)Cl(2) at room temperature. The resulting compound is the salt of the 2,6-bis-(2-meth-oxy-phen-yl)pyridinium cation and 0.5 equivalents of a hexa-bromido-dicuprate(II) dianion. Both meth-oxy groups of the cationic pyridinium moiety are directed towards the N atom of the pyridine ring as a result of intra-molecular N-H⋯O hydrogen bonds. The centrosymmetric hexabromidodicuprate dianion possesses a distorted tetra-hedral geometry at the copper ion. The Cu-Br bond lengths are 2.3385 (7) and 2.3304 (7) Å for the terminal bromides, whereas the bond length between the Cu atom and two bridging bromides is slightly longer [2.4451 (6) Å].
