Abstract: The asymmetric unit of the title compound, (C₆H₈N)₂[SbCl₅], consists of an SbCl₅ anion linked to two 4-methylpyridinium cations by two N-HCl hydrogen bonds. The bond lengths and angles around the Sb^III ion describe a disorted square-pyramidal coordination geometry. In the crystal structure, weak - stacking interactions occur between inversion-related pyridine rings [Cg1Cg1 = 3.788 (2) Å and Cg2Cg2 = 3.522 (2) Å, where Cg1 and Cg2 are the centroids of the two pyridine rings].
