title: 1-Hexyl-1,3,6,8-tetra-aza-tricyclo-[4.3.1.1]undecan-1-ium iodide.
abstract: In the title compound, C(13)H(27)N(4) (+)·I(-), the ethyl-ene bridge is distorted from the ideal D(2d) symmetry wherein an N-C-C-N planar bridge, around whose C-C bond the C-N and C-H bonds are exactly eclipsed, is disordered over two sites with equal occupancies. In both disorder components, the hexyl chain adopts an ideal all-trans conformation. In the crystal, adjacent ions are connected by C-H⋯I hydrogen bonds, forming ionic pairs that are further linked into chains along [101] via a second C-H⋯I inter-action.
