title: 2,3,3-Trimethyl-1-[4-(2,3,3-trimethyl-3H-indol-1-ium-1-yl)but-yl]-3H-indol-1-ium diiodide.
abstract: In the crystal of the title salt, C(26)H(34)N(2) (2+)·2I(-), the dication lies on a center of inversion that exists along the mid-point of the butyl chain; its five-membered ring is approximately planar (r.m.s. deviation = 0.011 Å). In the crystal, the iodide anion is disordered over two positions in a 1:1 ratio.
