The title compound, C 3 H 10 N + ÁBr À , is composed of hydrogenbonded (CH 3 ) 3 NH + and Br À ions. The N, Br and CH of one methyl substituent lie on a mirror plane that relates the two remaining CH 3 groups by symmetry.

✦ Synopsis
The crystal structure of the title compound, C 3 H 10 N + ÁI À , originally determined by Sheldrick & Sheldrick [Acta Cryst. (1970), B26, 1334-1338], has been redetermined at 93 K. Both ions lie on a mirror plane. They form N-HÁ Á ÁI hydrogenbonded units in the crystal structure.
