The title compound, C36H76N+·Br-, has two diad-related n-C18 methylene chains bonded to a central quaternary N atom which lies on the diad axis. The N atom and first three C atoms on each side of it form a coplanar zigzag. At the third C atoms, the chains bend sharply so that the backbones of the two parts of each chain subtend an angle of 129°. The chains continue outwards as coplanar zigzags.
