In the hexa-chlorido-animonate anion of the title compound, (C(12)H(17)N(2)O)[SbCl(6)], the Sb(5+)ion is in a slightly distorted octa-hedral coordination. In the 4-(2-methyl-piperidine-1-carbon-yl) pyridinium cation, the dihedral angle between the mean planes of the pyridine and piperzine rings is 66.3 (3)°. The mean plane of the carbonyl group is twisted by 80.5 (7)° and 42.7 (4)° relative to the mean planes of the pyridine and piperzine rings, respectively. The methyl group is in an R configuration relative to the piperidine ring which is in a slightly distorted chair conformation. The crystal packing is stabilized by N-H⋯O hydrogen bonds between cations, which form infinite zigzag chains parallel to [010].
