3,3′-Bis(3-methyl­but-2-en­yl)-1,1′-propylene­dibenzimidazolium Dibromide Monohydrate

Abstract

The title compound, C<inf>20</inf>H<inf>34</inf>N<inf>4</inf> 2+·2Br-·H<inf>2</inf>O, was synthesized from 1,1′-propylendibenzimidazole and 1-bromo-3-methylbut-2-ene in dimethylformamide solution. The compound crystallizes with one water molecule and two Br- ions in the asymmetric unit. The crystal structure is stabilized by inter-and intramolecular O-H⋯Br and C-H⋯Br hydrogen-bonding interactions. © 2006 International Union of Crystallography. All rights reserved.
