title: (S)-2-(Pyrrolidinium-2-ylmethyl-sulfan-yl)pyridinium dibromide.
abstract: In the title compound, C(10)H(16)N(2)S(2+)·2Br(-), the pyrrolidine ring displays an envelope conformation, with the flap C atom lying 0.484 (5) Å out of the plane of the rest of the pyrrolidine ring. The thio-ether group connects the pyridine ring and the 2-methyl-pyrrolidine group. Both pyrrolidine NH bonds form hydrogen bonds to the bromide anions. These hydrogen bonds link the cations and anions in a helical chain along the c axis.
