Abstract

The reaction of CuX2 (X = Cl or Br) with 3,5-dimethylpyridine in aqueous acids (HX; X = Cl or Br) yields bis(3,5-dimethylpyridinium)tetrachlorocuprate and tetrabromocuprate salts, 1 and 2, respectively. The crystal structures of the two compounds belong to the monoclinic space group Cs/2. In the crystal structure of both 1 and 2, the cations and anions are aggregated via classical hydrogen bonding of cationic pyridinium hydrogens and X- of CuX42- and non-classical (p)C―H•••X intermolecular interactions into a layer supramolecular architecture parallel to c axis.
