A quaternary ammonium salt of [Bz6HPy] [BzPy] [CuCl4] ([Bz6HPy] + and [BzPy] + is an onium ion of benzylpiperidine and benzylpyridine) was synthesized. The composition and structure of the synthesized product were characterized by elemental analysis, infrared spectroscopy, electron spray mass spectrometry and X-ray diffractometer.The results show that the synthesized quaternary ammonium salt is orthorhombic and the space group Pbca has unit cell parameters of a = 1.581 8 (2) nm, b = 1.762 5 (2) nm, c = 1.841 7 (3) nm, V = 5.134 5 (5) nm3, Z = 8, Dc = 1.428 g / cm3, GOOF = = 0.051 2, wR2 = 0.143 7. The quaternary ammonium salt molecule consists of one tetrahedral [CuCl42] -anion, one [Bz6HPy] + cation and one [BzPy] + cation; two adjacent [BzPy] + Cations form dimers through the π ... π stacking between the pyridine rings, while the anion and cation form a network structure via CH ... Cl and NH ... Cl hydrogen bonds.
