title: (S)-1-(2-Ammonio-3-methyl-butyl)-1,2-dihydro-pyridin-2-iminium dibromide.
abstract: In the title compound, C(10)H(19)N(3) (2+)·2Br(-), the plane of the three butyl C atoms nearest to the pyridine ring is almost perpendicular to the ring [dihedral angle = 84.80 (2)°]. The N atom of the ammonium group is displaced by 1.150 (8) Å from the plane of these three C atoms. The iminium N atom lies on the opposite side of this plane. The crystal structure is stabilized by hydrogen bonds between the N and Br atoms, as well as by inter-molecular C-H⋯Br inter-actions.
