Abstract

The title salt, (C₁₉H₁₈NO₂)₂[Cu₂Br₆], was obtained from an attempt to synthesize the copper(II) complex of 2,6-bis(2-methoxyphenyl)pyridine (L) from a reaction between CuBr₂ and one equivalent of L in CH₂Cl₂ 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].

Comment

An attempt to synthesize copper(II) complex of 2,6-bis(2-methoxyphenyl)- pyridine in CH₂Cl₂ unexpectedly yielded the ionic complex (C₉H₁₈NO₂).0.5(Cu₂Br₆). The single crystals of the title compound crystallizes in the orthorhombic unit cell in space group P_bca. Each asymmetric unit cell contains one molecule of 2,6-bis(2-methoxy- phenyl)pyridinium cation and half a molecule of hexabromodicuprate(II). Crystallographic data of the title compound reveals intramolecular N—H···O hydrogen bonds forcing both methoxy groups to be in close proximity to the nitrogen atom of the pyridinium ring (N···O distances of 2.625 (4) and 2.630 (4) Å). The pyridinium and two methoxyphenyl rings are almost co-planar, having the dihedral angles between them of 7.5 (5)° and 15.0 (5)°. In addition, weak intermolecular π-π stacking interactions between pyridine and phenyl moieties of the neighboring molecules with centroid-centroid distances of 3.649 (2) and 3.850 (2) Å are present.

Note that the centroid of the complete dianion coincides with the inversion center. Moreover, the hexabromodicuprate(II) dianion displays a distorted tetrahedral geometry at both copper(II) ions with Cu—Br bond distances of 2.3385 (7) and 2.3304 (7) Å for terminal bromides, and 2.4451 (6) Å for bridging bromides, respectively.

The neutral compound 2,6-bis(2-methoxyphenyl)pyridine has been previously reported (Silva et al., 1997) and their crystals were obtained from an ethyl acetate solution. The published crystal structure reveals that both methoxy groups are on opposite sides of the pyridine nitrogen to avoid the N···O lone pair repulsion. In addition, copper(II) complexes of the related ligand 2,6-bis(2'- hydroxyphenyl)pyridine have previously been synthesized and characterized (Steinhauser et al., 2004).

Experimental

The title compound, (C₉H₁₈NO₂).0.5(Cu₂Br₆) (1), was prepared from a reaction of CuBr₂ (0.5 mmol) with one equivalent of 2,6-bis(2-methoxyphenyl)pyridine (0.5 mmol) in dichloromethane (30 ml) at room temperature for 3 h. The reaction solution was filtered to remove any unreacted CuBr₂. X-ray quality single crystals were obtained from slow evaporation of a dichloromethane solution of 1 at room temperature.

Special details

Geometry. All standard uncertainties (except dihedral angles between l.s. planes) are estimated using the full covariance matrix. The standard uncertainties in cell dimensions are are used in calculating the standard uncertainties of bond distances, angles and torsion angles. Angles between l.s. planes have standard uncertainties calculated from atomic positional standard uncertainties; the errors in cell dimensions are not used in this case.
