3,3 '-bis(3-methylbut-2-enyl)-1,1 '-propylene-dibenzimidazolium dibromide monohydrate

Abstract

The title compound, C27H34N42+center dot 2Br(-)center dot H2O, 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 center dot center dot center dot Br and C-H center dot center dot center dot Br hydrogen-bonding interactions.
