Crystal structure, and crystal supramolecularity of Bis (3,5- dimethylpyridinium)‎ tetrahalocuprate (II)‎ [halide = Cl or Br]

Abstract EN

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 and2, 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 actions and anions are aggregated via classical hydrogen bonding of cationic pyridinium hydrogen's and X- of CuX42- and non-classical (π)C―H•••X intermolecular interactions into a layer supramolecular architecture parallel to c axis.
