Bis(3-methyl­pyridinium) tetra­(chlorido/bromido)cuprate(II)

The structure of the title salt, (C(6)H(8)N)(2)[CuCl(3.4)Br(0.6)], consists of two 3-methyl­pyridinium cations and a distorted tetra­hedral [CuCl(3.4)Br(0.6)](2−) dianion. Substitutional disorder with Br is exhibited for three of the Cl atoms of the anion, giving a mixed chloride/bromide cuprate(II)...

Sumario:The structure of the title salt, (C(6)H(8)N)(2)[CuCl(3.4)Br(0.6)], consists of two 3-methyl­pyridinium cations and a distorted tetra­hedral [CuCl(3.4)Br(0.6)](2−) dianion. Substitutional disorder with Br is exhibited for three of the Cl atoms of the anion, giving a mixed chloride/bromide cuprate(II) anion. In the crystal, inter­molecular N—H⋯Cl hydrogen bonds link two cations to one anion, forming a three-ion aggregate. These are connected into a supra­molecular chain along the b axis via π–π inter­actions between the pyridinium rings [centroid–centroid distance = 3.743 (3) Å].
