Bis[2,6-bis­(2-meth­oxy­phen­yl)pyridinium] di-μ-bromido-bis­[dibromidocuprate(II)]

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-meth­oxy­phen­yl)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...

Sumario: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-meth­oxy­phen­yl)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-meth­oxy­phen­yl)pyridinium cation and 0.5 equivalents of a hexa­bromido­dicuprate(II) dianion. Both meth­oxy groups of the cationic pyridinium moiety are directed towards the N atom of the pyridine ring as a result of intra­molecular N—H⋯O hydrogen bonds. The centrosymmetric hexabromidodicuprate dianion possesses a distorted tetra­hedral 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].
