title: (S)-2-Amino-1-(pyrrolidinium-2-ylmeth-yl)pyridinium dibromide.
abstract: In the title compound, C(10)H(17)N(3) (2+)·2Br(-), the pyrrolidinium ring displays an envelope conformation, with the flap N atom lying 0.564 (6) Å from the mean plane of the remaining four C atoms. The attached methyl-ene C atom, which connects the pyrrolidinium ring and the 2-amino-pyridine group, is displaced from the plane of the four pyrrolidinium C atoms by 0.811 (8) Å in the same direction as the pyrrolidinium N atom. The amine N lies on the opposite side of this plane.
